"Add it!" Chen Wanrong knew that Chen Zairong was very curious and signaled him to take action.

Chen Zairong, who received Chen Wanrong's permission, said, "I added it." He threw the soda ash in his hand into the barrel, and a slight sound was heard and water splashed everywhere.

"You're not gentle either." Chen Laoshi looked a little unhappy.

Chen Wangshi gently stroked Chen Zairong's shoulder and said, "Zairong, use less force, the water splashes everywhere, be careful to splash on people."

Chen Wanrong had to teach Chen Zairong the key points again, grabbed a handful of soda ash and evenly sprinkled in the bucket: "You need to sprinkle like this, sprinkle evenly. Don't use force, just sprinkle it."

"There are stones, there are stones! There are really stones in the water! It's amazing!" Chen Zairong pointed at the little calcium carbonate precipitation in the bucket in surprise, his eyes staring like copper bells, exactly the same as Chen Laoshi's expression when he first saw this scene yesterday.

The chemical reaction between ripe lime and soda ash is very fast and is completed instantly. Chemically called instant reaction, calcium carbonate slightly soluble in water appears in the water instantly, and floats in the water due to its low solubility. Chen Zairong screamed, as if a playful child suddenly had his beloved toy.

"Worry, your ears are deaf." Chen Housheng scolded and began to make the master's poem: "Can you still call a spell if you are not amazing? Turning soda ash into an irrelevant stone is the magic of magic! Wanrong, right?" Looking at Chen Wanrong, eagerly looking forward to Chen Wanrong's affirmation.

The main component of limestone is calcium carbonate, and the calcined quicklime is calcium oxide. Quicklime reacts with water to form calcium hydroxide, and hydrated lime then reacts chemically with soda ash to form filamentous alkali and calcium carbonate, and returns to the starting point. The statement that sews stones in water is actually correct.

Chen honestly copied Chen Wanrong's statement to show off his character and pretended to be a master, which made people laugh. Chen Wanrong satisfied his wish: "Dad, that's it."

"Old man, you are full of a big-tailed maggot. Who doesn't know? I know too." Chen Wangshi glanced at Chen Laoshi who was drunk.

Chen Laoshi couldn't help but feel a little worried: "I didn't tell you again." He moved a few steps and stayed away from Chen Wangshi.

Chen Zairong had a good understanding, and he could understand it immediately: "Brother, I understand! This is similar to making batter. You have to sprinkle the flour evenly, otherwise bumps will appear." He grabbed a handful of soda ash and evenly sprinkled it in the bucket. Although he had only been intern once, he was as old as a master.

It is very skillful to make batter in rural areas. A bowl of batter that can be made without bumps and is delicious. However, those who can’t make batter will appear without evenly sprinkle the flour. When you bite it, you often have a sound, and a ball of flour appears in front of you, as if it is snowing.

This metaphor is vivid and particularly suitable for farmers to understand. Chen Chen complained: "Wanrong, you didn't say it earlier, such a simple thing." He grabbed a handful of soda ash, rolled up his sleeves, and scattered it in the bucket, as if he was making a batter.

His neck was stretched long, his eyes were wide open, his sleeves were raised high, and his left hand was put on his waist. Chen Laoshi looked like a master. He looked so funny in secret that he picked up the stick and stirred it in the bucket. Without mixing equipment, he could only use the "full automation" method of human power.

Seeing Chen Laoshi's appearance, Chen Wangshi couldn't help but curl his lips and kept twitching, very disdainful.

Chen Wanrong was responsible for stirring, Chen Laoshi and Chen Zairong were responsible for sprinkling soda ash, and Chen Wang was responsible for visiting. The calcium carbonate precipitated more and more, and the barrel began to become turbid.

I did an experiment yesterday and it took not much time, and it was completed in just a short while. Today is a real production and making products, and there is a big gap between them. Such a turbid solution did not appear yesterday. Chen Laoshi took a cold breath in surprise: "Wanrong, what's going on? Didn't have so many stones yesterday? Wanrong, your spell is getting more and more powerful." He said very politely, with an admiration on his face, as if a believer met a god.

They are all the same chemical reactions, and the only difference is the amount of it is too much. Chen Laoshi praised it so much. Chen Wanrong was afraid that he would misunderstand it, so he quickly clarified: "Dad, it's all the same. I did less yesterday and more today. The difference is here. It's like the difference between a small bowl of porridge and a big pot of porridge."

"Porridge?" Chen Houshi patted the bucket thoughtfully, looking at Chen Wangshi, a trace of worry flashed in his eyes. Chen Wangshi glared at him and shook his head slightly, as if he was conveying some information.

"Mom, have you brought the rice bucket?" Chen Zairong looked at the wooden bucket in surprise: "I think this bucket looks familiar, and I can't remember it for a moment. Dad patted it and I remembered it. Mom, is there no rice?"

Chen Laoshi's face turned dark, and before he could speak, Chen Wang took over the conversation: "Zai Rong, what are you talking nonsense? Wan Rong wants a bucket, so we put the rice in a bag and free the bucket out to help the emergency."

Although Chen Laoshi knows how to work hard, he makes many buckets throughout the year, but there are no more buckets in his house except a rice bucket. "Wear a cool mat and sleeps with nothing on the bed; those who sell salt drink light soup." This is a portrayal of life in a poor family.

Chen Zairong didn't believe it and asked, "Mom, aren't you lying?"

Chen Wanrong knew that no matter whether his guess was true or false, he could not admit it now. If he had no rice, he would not go to study if he was worried. He smiled and said, "No matter how lucky he is, don't guess randomly, how could there be no rice at home? I'm at home all day, and I don't know whether there is any rice." In order to make him believe, his tone increased a lot, and he said it firmly, and anyone would believe it.

Chen Zairong said oh and stopped talking. Chen Laoshi and Chen Wangshi looked at each other and breathed a sigh of relief. Chen Wanrong saw it and thought that Chen Zairong's guess might be true, so he had to find an opportunity to confirm it.

In order not to bring in ripe lime, you need to overdos soda ash. Excessive soda ash does not have any major harm, and it can still be used to deal with the skin. If the ripe lime is too much, something will happen. Chen Wanrong probably is almost done, so he asked Chen Zairong to stop. Stir for a while, then knock the stick on the edge of the bucket and put it aside.

Chen Wanrong knew a lot about separation technology, but the current conditions do not have equipment, so he can only use the most original method: let it stand. Without stirring the solution, the calcium carbonate precipitates after a while and then the hot alkali solution can be scooped into the pot for heating.

"Wanrong, is it time to get the pot?" Chen honestly rubbed his hands and sought Chen Wanrong's opinions.

It's indeed time to prepare the pot, Chen Wanrong nodded: "Yes, dad."

"There is no extra pot at home, so you can only use a pot for cooking, and the big one." Chen Wangshi also came to ask Chen Wanrong for his opinion: "Wanrong, what do you think?"

This is a poor family. There is no extra pot at home. Even if you want to buy it, you don’t have the financial resources. You can only use a pot to cook. Chen Wanrong didn’t say anything: “Okay.”

Chen Zairong rushed to work: "I'll go wash the pot."

Chen Wangshi grabbed him: "I have washed it, Wanrong see if it works. Yesterday, I saw that you washed the wooden bucket for so long, and it must be clean. I washed it for a while, I am afraid it doesn't suit Wanrong's wishes. Wanrong, go and have a look."

She was so meticulous that she thought of everything and did the preparations well. Chen Wanrong felt warm in her heart and said, "Thank you, mom!"

"How much thanks? Just a little work." Chen Wang smiled, so happy that even the wrinkles on his face disappeared.

When I came to the stove, I saw that the three-foot pot was cleaned and looked very refreshing. Chen Wanrong couldn't help but praise: "Mom, you wash it so cleanly, it's quite suitable."

"I'm afraid I can't wash it clean, so I added some soda ash." Chen Wang was very relieved to get Chen Wanrong's affirmation.

Chen Zairong grabbed the edge of the pot and tried hard, and a black hole appeared on the stove. Chen Zairongfei rushed outside the house like a while, and Chen Wanrong and the other two kept chasing behind him, but they couldn't catch up. When Chen Wanrong and the other two arrived at the field, Chen Zairong had already put the pot on the stove hole and placed it.

Chen Wangshi pulled Chen Laoshi to pick up Chaihe, and Chen Zairong rushed to say, "Mom, you rest, I'll go." Without waiting for Chen Wangshi to express his opinion, he jumped far away. Looking at his back, Chen Wangshi was very happy: "This child!"

When Chen Zairong turned around, he had a large bundle of firewood in his hand. He put it in front of the stove and turned around and stood beside the bucket and looked into the bucket.

After a while, the solution in the bucket had obviously been layered, the upper layer was clear, and the lower layer was still turbid. Chen Wangshi and Chen Laoshi surrounded him and looked at the bucket, as if an anxious greedy cat was staring at the fish, wishing he would sit down immediately.

After half an hour, the calcium carbonate precipitated to the bottom of the barrel, as if it was stacked like mud and sand in the river. Chen Wanrong said, "Okay."

Chen Zairong waited for this sentence, grabbed the scoop and scooped the upper layer of clear solution and poured it into the pot. Chen Wang was busy raising the fire. When Chen Zairong finished scooping, Chen Wang also raised the fire, and the sound of whirring flames came out of the stove hole.
Chapter completed!
