Chapter 56: Beauty Invitation

"What are you watching?" Chen Laoshi's voice sounded. When Chen Wanrong saw that Chen Laoshi's neck stretched out, his eyes were full of surprise. He asked, "What are you watching? It seems like he is watching a hundred operas."

Not to mention, his metaphor is very vivid. Zheng Qing and the others' performances cannot be explained by watching a hundred operas. They should be the expressions and expressions that are fascinated by them.

"Who is watching a hundred operas? It's just nonsense! We are watching Wanrong make sulfuric acid." Chen Wang rolled his eyes to Chen Laoshi.

Chen Laoshi suddenly became confused and asked, "What is sulfuric acid?"

"You don't know sulfuric acid?" Chen Wang's face looked gloomy and raised his eyebrows and explained to Chen honestly: "Sulphuric acid is a good thing, a good thing, otherwise how could Wanrong do it?" She didn't understand what sulfuric acid was. After going around such a big circle, she said nothing except praising Chen Wanrong.

Qing'e wanted to laugh when she heard this, but fortunately Zheng Qing responded quickly. She touched her and didn't laugh. Otherwise, Chen Wangshi would be unable to hold her face.

"Brother, what are you looking at? You're so fascinated." Xiao Shangrong ran over with a confused look on his face and looked at the water basin. He had nothing but clear water.

Chen Wanrong asked, "Why are you here?"

"You are here to see the strange things. Can we not be curious? They are embarrassed to come and see them." Xiao Shangrong didn't intend to hide it from Chen Wanrong, and told the truth.

Chen Wanrong looked away, and the hired workers had long necks and their eyes were full of surprise. Han Huahua stood at the door, looking at this side, and saw Chen Wanrong looking at her, her face turned red and she quickly shrank back.

A bunch of people gathered here is already eye-catching, and Chen Wanrong's jar is so weird that it would be impossible for the hired workers to be curious.

They are all honest countrymen and are still related to their relatives. Chen Wanrong is embarrassed to take care of them too strictly, and it is strange during work hours. If it weren't for Chen Wanrong's boss, he would have been surrounded by him long ago.

"Look, it's true like a hundred tea dramas." Qing'e pointed at the water patterns in the water basin and was amazed.

Tea Hundred Plays need to be stirred with bamboo utensils, stirred into various shapes, lifelike. This is just water patterns driven by water vapor. One is art to please the mood, and the other is industrial phenomenon. The two cannot be compared at all. However, this does not hinder her from comparing.

"It seems like fish are swimming." Xiao Shangrong stared at the swelling water marks, very surprised.

Zheng Qing blinked her flexible eyes and asked, "Brother Chen, is there sulfuric acid?"

The fire just rose, the temperature rose, and the crystallization water began to fall off. It was not that fast, Chen Wanrong explained: "This is water vapor, and it will take a while to wait."

Chen Wanrong is an authority in this regard. He said whatever he said is. Although Zheng Qing was anxious, she still had to wait patiently. Qing'e said to Chen Wanrong: "Hey, smart people, let me tell you. If you don't say it, I'm sorry for the lady talking about you these days."

Zheng Qing's face was so irresistible that Zheng Qing's face turned red, her feet stomped on the ground, her right hand twisted on Qing'e's arm, and she said angrily: "Look, do you dare to say anything?" Feixia rushed to her face, her pretty face was angrily, and she was particularly charming and pitying.

When Chen Wang touched Chen Laoshi, he winked, grabbed Xiao Shangrong and walked away quickly. Chen Laoshi didn't understand, so he followed and asked, "Wife, what are you doing to touch me? I want to look at it for a while."

"You are a lump of wood, you can see this?" Chen Wangshi glanced at him in anger.

Xiao Shangrong saw Chen Laoshi's mysterious look and knew that he would not understand it if he didn't make it clear to him. He whispered a few words in his ear. Chen Laoshi turned his head and looked at Zheng Qing, then looked at Chen Wanrong, and kept touching his face: "Okay, okay!" He smiled so hard that he couldn't close his mouth, so he quickly followed Chen Wangshi.

After spending so long with Zheng Qing, Chen Wanrong has a lot of affection for her. Seeing her charming look, she couldn't help but feel itchy and asked, "Smart people, does she say bad things about me? Then I can't show her a show."

This is an alternative method of provoking. Chen Wanrong clearly wanted to ask Zheng Qing what he said, but he just asked him in a different way. Qing'e didn't know it was a plan, so he opened his mouth: "Good intentions are like a wolf's liver and lung..." Zheng Qing's reaction was much faster, and she covered Qing'e's mouth with her right hand and said angrily: "Don't say it!"

Qing'e also reacted. Unexpectedly, Chen Wanrong, a person who is sincere to everyone, had such ambitions and almost fell for it. He glared at Chen Wanrong fiercely.

Zheng Qing looked at Chen Wanrong, ashamed and at a loss. The elegant and graceful woman was gone, but the only one who couldn't stop squeezing her fingers.

Chen Wanrong had no idea what he could not understand. He couldn't bear to make her too embarrassed, so he changed the topic and said, "Sulphuric acid is coming out soon."

Although Qing'e and Zheng Qingming were masters and servants, they were like sisters, and they were very impressed by Chen Wanrong's intention to relieve their embarrassment, and immediately agreed: "Miss, look, there are more water patterns."

Zheng Qing's shyness was not gone, and she rubbed against Qing'e's side, a little further away from Chen Wanrong. Then she looked into the basin. She saw the water patterns folded one by one, and kept flipping. It looked very beautiful and smiled happily: "Brother Chen, is it sulfuric acid? Why didn't I see it?"

The temperature has risen a lot now, and copper sulfate should be decomposing, but the amount will not be too much. Besides, sulfur trioxide reacts with water to form sulfuric acid, while sulfuric acid is colorless and transparent, dissolved in water, and no matter how good the vision is, it cannot be seen. Chen Wanrong had to explain to her: "It's still too little now, and you can see it after waiting for more. In fact, from the appearance, there is no difference between sulfuric acid and water. If you want to know whether it is sulfuric acid, you have to check it."

Zheng Qing immediately showed the good morals of a good student and asked: "Brother Chen, how should I test this?"

There are many methods for testing sulfuric acid, but there are no conditions now. Chen Wanrong thought for a while and said, "When you do it more, I'll do it for you." After increasing the concentration, just one dehydration is enough to surprise her.

Zheng Qing never disobeyed Chen Wanrong, and gently pointed her head: "Thank you, Brother Chen!"

After saying a few words, his shame was gone, he no longer looked like a child, but he returned to the elegant and elegant woman.

This burning method is a long process and takes a lot of time. Chen Wanrong moved out three chairs in the house, and sat each one at a time. Qing'e put the chair in front of the stove and volunteered to be a handyman to raise the fire.

Zheng Qing sat next to Chen Wanrong, watching the changes in the basin without missing a single thing.

"Brother Chen, it seems that there is a lot of water." Zheng Qing had a strong observation ability and found something strange about the water basin.

The alum contains five crystal water, accounting for 36%. After heating, the crystal water separates out, enters the water basin through the spout, and then cools down again. The water naturally increases.

Chen Wanrongda admired her extraordinary observation from her heart: "The alum itself is white, and it turns blue because it absorbs water, which looks very beautiful. After heating, the moisture becomes water vapor again, and mixes it in the water basin, so it is naturally more."

The alum Chen Wanrong now refers to copper sulfate, not to the alum in the complete sense. If he explains it completely according to the chemical definition, even though Zheng Qing is extremely smart, he may not be able to fully understand it, and it is as simplified as possible for her to understand.

Zheng Qing showed Bingxue's clever side and gently tapped her head: "Brother Chen, is it the same as when the cloth is soaked in water, and the water is dripping again? It's just that the method is different."

Although the two are very different, it is extremely rare to understand this way. Especially with different methods, this is even more insightful. Chen Wanrong looked at her in surprise and praised: "It's this principle, it's this principle."

After a long wait, the water lines in the basin became less and less. Chen Wanrong knew that it was almost done and asked Qing'e to retreat. Although Qing'e liked to make fun of Chen Wanrong, she was extremely serious about the matter and did not compromise and eliminated the fire.

Chen Wanrong removed the brick and placed the basin on the ground. As soon as the spout left the basin, an unpleasant smell ejected from it. Zheng Qing hurriedly covered her nose.

Carrying the basin, Chen Wanrong walked straight into the house. Zheng Qing and his servant hurriedly followed him, wanting to see what was going on. Chen Wanrong put the basin on the table. Zheng Qing looked at the basin and asked, "Brother Chen, what should I do next?"

She looked curious, and she knew without thinking that she wanted to see the verification of sulfuric acid. Chen Wanrong really couldn't bear to let her wait and said, "I'll verify it for you."

"Thank you, Brother Chen!" Zheng Qing brimmed her high-highlights, and was overjoyed.

Qing'e was also curious and muttered: "This is almost the same!"

If there is litmus reagent, it would be enough to surprise her just by changing the color. Now there is no finger reagent, so this method cannot be used. Find something to do some chemical reactions. Sodium ash will release carbon dioxide when encountering sulfuric acid, and the blisters are also surprised, which is enough to comfort her.

Having a certain idea, Chen Wanrong found a bowl, grabbed some soda ash, put the soda ash in the bowl, scooped some solution and poured it into the bowl. Bubbles immediately appeared in the bowl, like bubbles spit out by fish, which looked very beautiful.

For us modern people, this is nothing. For Zheng Qing, the Tang Dynasty, there is nothing in the bowl, but bubbles can appear. That is a very magical thing. Miaomu looked at the bowl, and didn't even know that it was turned, and her face was full of surprise.

Qing'e's performance is even better than her, even more so, her eyes wide and her mouth opens, without even caring about her ladylike image.

Until there were no more bubbles, Zheng Qing and his servant realized. Qing'e hesitated and said, "What's the reason for this?"

This is exactly what Zheng Qing was asking. Miaomu looked at Chen Wanrong and waited for Chen Wanrong to give an answer. Chen Wanrong would not disobey her. She smiled and said, "Sodium ash will undergo chemical reaction when encountering sulfuric acid, and will produce carbon dioxide, and bubbles will appear."

If they really need to explain in detail, they will definitely not understand it. If they can be brief, they will be simple. Although Zheng Qing is extremely smart and can't understand it, she did not ask questions, but just nodded slightly. She thought that Chen Wanrong would not lie to her, although she didn't understand, what Chen Wanrong said must be the truth, which is enough.

"Smart people, can you change some tricks for me to see?" Qing'e glanced at Zheng Qing as she spoke, and she couldn't understand her meaning.

Zheng Qing understood what she meant, her pretty face turned red, and she twisted her arm lightly, but she didn't object.

This is the first part of sulfuric acid that Chen Wanrong made in the Tang Dynasty. Knowing that its properties will not change, he still wanted to verify it with his own eyes. After pondering for a moment, he nodded and said, "Okay, let me show you the dehydration." He knew that they would ask questions, but before they could ask, they would explain first: "Dehydration is one of the main characteristics of sulfuric acid, and it requires concentrated sulfuric acid. The current sulfuric acid does not meet the requirements. Concentrated sulfuric acid will turn yellow when it is stuck on paper or on cloth sheets, like withered leaves."

In the eyes of ancient people, paper or cloth was already very dry and could actually suck out water. Although Zheng Qing was knowledgeable, she was still difficult to understand. She blinked her beautiful eyes: "Brother Chen, are you not lying? Then there is water?"

"Just tell lies!" Qing'e didn't believe it at all.

Chen Wanrong said seriously: "Do you think I'm lying?"

Qing'e looked at Chen Wanrong and said, "Who knows?"

"Qing'e, don't talk nonsense, Brother Chen is not that kind of person." Zheng Qing still trusted Chen Wanrong unconditionally.

Chen Wanrong explained: "Now I have to increase the concentration of sulfuric acid. There is no better way, I can only rely on zeolites." Another way is to directly heat the method. The boiling point of sulfuric acid is high, and the sulfuric acid will not evaporate after the water evaporates. The concentration will be increased by heating.

But there is one disadvantage of this method, that is, evaporation of water will take away sulfuric acid and cause losses. Sulfuric acid is very precious to Chen Wanrong, and he would rather spend more time than lose sulfuric acid. Besides, the current sulfuric acid concentration is less than 10%, and the loss will be very large if he uses heating method. This loss is not something Chen Wanrong can bear now. Choosing a zeolite is troublesome, but the benefits are huge.

I returned to the house, took out a few zeolites and put them in the stove hole to burn. I cleaned the bowl just now and scooped half a bowl of sulfuric acid. I just did an experiment, and I didn’t need to raise all the concentration. Besides, this dilute sulfuric acid can be used again. After making it multiple times, the concentration will naturally be much higher. It will save you much trouble when you strengthen it again.

The charcoal fire in the stove cave was still very strong. When the zeolite was thrown in, it made a hissing sound in just a while. The water soaked on the zeolite and rolled on it. It looked very beautiful and very attractive. Qing'e was so excited that she clapped her little hands: "Miss, look, it's so fun."

"We used to be fun, and that's the same." Zheng Qing seemed to have returned to her happy childhood, with strange light shining in her wonderful eyes.

Until there was no longer water vapor on the zeolite, Chen Wanrong clamped it out with pliers and placed it on the ground and looked at it. He immediately became dumbfounded: "No, you can't do this."

Qing'e screamed and asked impatiently: "Why? If you don't do it, what do we think?" In a hurry, he even forgot to make fun of Chen Wanrong's smart people.

Although Zheng Qing didn't say anything, disappointment was already written on her face, aiming at Chen Wanrong.

Chen Wanrong had to explain to them: "Look, there is a lot of ash on it. If you put it down, it will not only bring in impurities, but also lose sulfuric acid. The wood ash is alkali and will react with the acid."

Just to demonstrate the dehydration, the loss can still be withstood. However, the zeolite method was chosen by Chen Wanrong to increase the concentration of sulfuric acid. In this way, all the sulfuric acid concentrations cannot be increased, and it is impossible to make Chen Wanrong not anxious.

Chen Wanrong hadn't thought about this problem. He used to think that as long as there was a zeolite, it would burn it with fire and cool it down, and then the water could be sucked off. After repeated repeated times, the concentration of sulfuric acid could be increased. Only when things were about to happen did they find that it would not work, and they were so anxious that they scratched their heads.

"Brother Chen, don't worry!" Zheng Qing comforted Chen Wanrong and helped him out: "It's not difficult to have any dust, you can burn it with charcoal."

It really woke up the dreamer. Chen Wanrong patted his forehead lightly and said happily: "Thank you, I'll help me think of such a good way. I have to buy charcoal."

I have everything at home, but there is no charcoal fire. There is nothing I can do except buy it.

Zheng Qing then made an idea: "Brother Chen, you can use a rack to put the zeolite on it and raise the fire below, so it will not get ashes, but also convenient."

This idea is not good, it is very good. Chen Wanrong nodded: "What a good idea! This is a good idea! It's good to use iron for this rack, but it's a bit difficult to do. I'd better go find Manager Yuan to cook one for me."

Seeing Chen Wanrong's eagerness to do business, Zheng Qing was understanding and said goodbye: "Brother Chen, then I won't bother you anymore, you'll be busy first."

Chen Wanrong is now eager to solve the problem, so he has no intention of keeping them, and smiles: "Then let's go slowly."

"Brother Chen, be polite!" Zheng Qing bowed and said with a fist: "When it comes to charcoal, there are still some in our family. If Brother Chen thinks it is suitable for use, you can come and take it. This thing will only be used in winter, and it will be stored."

There is something for sale in charcoal, so there is no need to go to her house to get it. Chen Wanrong opened his mouth and refused. Seeing her blinking her bright eyes at him, full of expectations, and could not bear to refuse her kindness, so he had to say, "Okay, then you'll have to worry."

Zheng Qing was full of joy and Zhan Yan smiled: "Brother Chen, I'll prepare it for you, come and get it tonight."

If you get a charcoal, you will do whatever you want, and you don’t have to go to the evening. Chen Wanrong is not good at her, so he has to say, “Okay, I will definitely come to get it to the evening.”

"Brother Chen, let's go!" Zheng Qingyu waved her hand and went side by side with Qing'e.
