After a while, water splashed in the bucket and the white water vapor dissipated. Chen Wanrong knew that the time was almost right, so he walked over quickly. He came to the bucket and looked into the wooden bucket. The small half of the bucket of water suddenly decreased. This was because the water participated in the chemical reaction. Before Chen Wanrong could speak, the clever Chen Zairong had already run away with the bucket and ran away while running: "Brother, I have to add water, I'll carry it."

The water is less and it is oversaturated. The ripe lime cannot dissolve anymore and is deposited at the bottom of the barrel. It is a thick layer. Adding water is the first priority at present. Although Chen Zairong has no common knowledge of chemicals and does not know the meaning of solubility, he still has experience accumulated in daily life. You can tell at a glance that it is necessary to add water.

Chen Wanrong found a wooden stick, went to the well and washed it a little with water. When he returned to the bucket, Chen Zairong had already added the water. Chen Wanrong rolled up his sleeves and prepared to stir and speed up the dissolution rate.

"Brother, I'll do it." Chen Zairong stretched out his hand, grabbed the wooden stick, and stirred it in the bucket.

This time, Chen Wanrong doesn’t need to remind him. Stir completely according to the requirements of the preparation reagent, stir the stick slowly, and the water flows slowly.

Chen Houshi didn't know the requirements of chemical operations, so he urged him: "No matter how glorious you are, where are you using your strength? Make it faster, if you make it so hard, it will be dark."

"Dad, you can't be fast, it doesn't meet the requirements if it's fast. Brother, is that right?" Chen Zairong explained with a smile: "Dad, you're not stirring the cesspool with lime. The water splashes out and burns your legs. Have you forgotten? If you stir it like this, nothing will happen."

He was talking about Chen Laoshi's edible pits with lime. How much effort Chen Laoshi had to use, the water flowed too fast, and one was not easy to splash out. Although he retreated quickly, he still splashed on his leg and burned a large area.

When Chen Laoshi mentioned this, he felt a little embarrassed and said stubborn: "Who told you that I don't know?"

Chen Wang laughed and gave Chen a blank look: "Old man, how long does it take to cook your mouth?"

Chen Houshi cleverly chose to remain silent and no longer responded.

Chen Wanrong looked into the bucket and signaled Chen Zairong to stop: "Okay." Chen Zairong then tapped the wooden stick on the edge of the bucket a few times, and put the wooden stick aside.

Limestone cannot be 100% pure and contains a large amount of impurities, which will affect the content of lime. After chemical reactions, quicklime has become ripe lime, but these impurities do not participate in the reaction. They float in water and after stirring, they are turbid like mud, and they cannot even see the bottom of the barrel.

Chen Zairong had heard of the fact that the stones in the water were long ago. He was so curious that he could no longer hold back and picked up the soda ash: "Brother, I'll add it now and look at the stones in the water."

An ordinary chemical reaction was strange and strange in the eyes of the ancients, and it was strange and complicated, and it was never seen or heard of. It was normal for him to be so anxious. If an alchemist was a elixir, he would call chemical reactions a Taoist magic and immortal method, boasting everywhere and fooling the people.

Chen Wanrong hurriedly stopped him: "Zairong, you can't add it now. If you add it now, you will not be able to see the stones in the water." Chen Zairong asked questions and said it first to relieve his doubts.

Unexpectedly, Chen Wanrong's kindness was in vain. Chen Zairong looked nervous: "Brother, why is this? Could it be that you forgot the immortal magic?"

The magical thing that alchemists call Taoist magic and immortal techniques is actually chemical reactions. Chen Wanrong used this to relieve his embarrassment. He didn't expect to give Chen Zairong some advice. He smiled and said, "How could I forget it? The bucket is so turbid, and you can't see it even if you grow stones."

"Brother, what should I do?" Chen Zairong's eyes widened so anxiously.

This is a very simple problem, and it is effortless to solve it. Chen Wanrong looked at the wooden barrel and said, "It's time to wait until the barrel is clarified. First, treat the soda ash and crush the large pieces."

The ancient soda ash was formed naturally in salt lakes. It was impossible to purify it when the ancients adopted it. The impurities were more than artificially synthesized, and there were many blocks. If they were not crushed, they would not be fully reacted, and the other would take more time. This is equivalent to the preliminary preparations in chemical production and crushing raw materials, which is very necessary.

Chen Zairong was even more anxious than the monkey who was eager to pick ripe peaches. When he heard this, he quickly released the soda ash and ran away as if flying. Chen Wang asked curiously: "Zairong, what are you going to get?"

"Rolling pin!" Chen Zairong's voice came from afar.

Chen Laoshi's eyes shone and he praised: "This is a good idea. Didn't the soda ash in the past be crushed with a rolling pin? Only when Rong can he think of this idea, he will come out." Finally, he didn't forget to praise his dear son.

The Tang Dynasty did not have suitable crushing equipment. Chen Wanrong was not familiar with the life of the Tang Dynasty and was thinking about how to break soda ash. Chen Zairong had already thought about this kind of reaction ability, which was indeed superior to others, and people had to convince him.

When Chen Zairong turned around, he not only had a rolling pin but also a round wooden board. Chen Laoshi saw the wooden board. He was the bottom of the barrel for making wooden barrels. He looked very unhappy: "Zairong, why do you take the bottom of the barrel? Take it back quickly."

"Dad, how can I crush this thing without this? Dad, I see that it is the right size and length of this thing." Chen Zairong happily sang the bottom of the bucket.

Chen Wanrong saw that Chen Zairong was right. The bottom of the bucket was really suitable. However, it would be appropriate to find anything. Chen Wanrong didn't want Chen Laoshi to feel sorry for: "Zairong, don't use it, I'll find one."

Chen Laoshi touched his forehead: "Wanrong, don't look for it, just use it. Wouldn't it be just a little wood, and it takes a while?"

Yan Lai was still a little reluctant, so Mrs. Chen quickly agreed: "It's done after using it. Old man, how distress do you feel?"

"Who said I feel distressed? Use it, use it now." Chen Houshi was so excited by Chen Wangshi and was very generous.

Chen Zairong was determined to see the novelty of stones in the water, so he ignored it. He put the bottom of the bucket on the stove, grabbed the soda ash and sprinkled it on it, pushed the rolling pin horizontally, and pushed it over it. The blocky soda ash immediately broke into small pieces, and some of the small pieces had already turned into powder.

The rolling pin pushed back and forth on it. After a few rounds, a handful of soda ash had turned into powder. Chen Wanrong found a clean and dry wooden basin and carefully swept the soda ash into the wooden basin.

Chen Zairong felt that this matter was fresh and fun, and his interest increased greatly, so he wrapped it all. He kept grabbing the soda ash and sprinkled it on the bottom of the bucket, crushing it with a rolling pin.

The benefits of practicing martial arts were once again demonstrated. The soda ash he treated was as fine as flour, even if it was treated with a modern crushing machine, it was just like this. Chen Wanrong was once again impressed by the power and wisdom of the ancients.

The purity of natural soda ash will not be very high, and 80% of it is already very impressive. Consider the loss. It takes more than ten kilograms of hot ash to make ten kilograms of hot ash. Chen Zairong treated almost fifteen kilograms, which was enough to make it. Then he gave up.

It took a lot of time to process the soda ash, and it took half an hour to finish the treatment. The lime solution had already precipitated and a thick layer of impurities had accumulated at the bottom of the barrel.

Just as Chen Zairong and Chen Wanrong were dealing with soda ash, Chen Laoshi and his wife went to wash an old wooden bucket. Chen Wanrong picked up the scoop and prepared to scoop the lime solution into the old bucket. Chen Zairong couldn't stop crying, "Brother, I'll do it." He grabbed the scoop with his hand and scooped the solution into the old bucket.

After scooping the solution, it is time to add soda ash to carry out the last chemical reaction. Chen Zairong jumped over, took the wooden basin containing soda ash and placed it on the edge of the bucket. He grabbed the soda ash with his right hand, opened his eyes wide open, and prepared to watch the magical scene of "Stones in the Water".

Looking at Chen Zairong's anxious look, Chen Wanrong couldn't help but feel funny. The modern chlor-alkali industry produces hot alkali by electrolyzing salt water. If Chen Wanrong uses soda ash and lime to produce hot alkali, it will be a loss to wear it because soda ash is more expensive than hot alkali.
