    After a while, water stopped splashing from the bucket and the white water vapor dissipated. Chen Wanrong knew that the time was almost up and walked over quickly.  When he came to the bucket, he looked into the bucket and saw that the water in the small bucket suddenly lost a lot. This was because the water participated in the chemical reaction. Before Chen Wanrong could say anything, the clever Chen Zairong had already ran away with the bucket.  He ran and said, "Brother, we need to add water. I'll carry it."

    There is less water and it is already oversaturated. The slaked lime can no longer dissolve and is deposited in a thick layer at the bottom of the barrel. Adding water is the first thing to do now.  Although Chen Zairong has no knowledge of chemistry and does not know the meaning of solubility, he still has accumulated experience in daily life. He knows at a glance that he needs to add water.

    Chen Wanrong found a wooden stick and went to the well to wash it 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 to speed up the dissolution.

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

    This time, there was no need for Chen Wanrong to remind him. He stirred exactly as required to prepare the reagents. The stick stirred slowly and the water flowed slowly.

    Chen Laoshi didn't know the details of chemical operations, so he urged him: "Zairong, where have you used all your strength? Stir faster. It will be dark by the time you stir like this."

    "Dad, you can't go too fast. Faster than meets the requirements. Brother, is that right?" Chen Zairong explained with a smile: "Dad, you mixed the lime with the manure pit, but you stirred it wrong. The water splashed out and burned your legs.  , Have you forgotten? If you stir it up like this, nothing will happen."

    He was talking about a time when Chen Laoshi used lime to patch up a manure pit. Chen Laoshi used as much strength as he could, but the water flowed too fast and one of the water splashed out.  Although he retreated quickly, it still splashed on his leg and burned a large area.

    When this matter was brought up, Chen Laoshi was a little embarrassed and said hard: "Who told you that I didn't know?"

    Mrs. Chen Wang laughed out loud and rolled her eyes at Chen Laoshi: "Old man, how long did it take for your mouth to be cooked to pieces?"

    Chen Laoshi wisely chose silence 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 lot of impurities, which will affect the lime content.  After chemical reaction, quicklime has turned into slaked lime, but these impurities did not participate in the reaction and floated in the water. After stirring, it became turbid like mud, and even the bottom of the barrel could not be seen.

    Chen Zairong had heard about the matter of stones growing in the water a long time ago. He was so curious that he couldn't hold it back any longer. He picked up the soda ash and said, "Brother, I'll add it right now and see if there are stones growing in the water."

    An ordinary chemical reaction, in the eyes of the ancients, was all kinds of strange and wonderful, unseen and unheard of. It is normal for him to be so eager.  If you are an alchemist, you will call chemical reactions Taoist magic and brag about it to deceive the common people.

    Chen Wanrong hurriedly stopped him: "Zairong, you can't add it now. If you add it now, you won't see the rocks growing in the water." Chen Zairong did not allow Chen Zairong to ask questions, but spoke first to clear up his doubts.

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

    The magical things that alchemists call Taoist magic are actually chemical reactions. Chen Wanrong used this to relieve his embarrassment. Unexpectedly, he actually used it to explain to Chen Zairong. He looked anxious and said with a smile: "How could I forget?  What? The barrel is so turbid, you can¡¯t even see the stones growing out of it.¡±

    "Brother, what should we do?" Chen Zairong's eyes widened in anxiety.

    This is a very simple problem, and it is easy to solve. Chen Wanrong looked at the barrel: "Just wait, wait until the barrel is clarified. First, process the soda ash and crush the large pieces."

    Ancient soda ash was naturally formed in salt lakes. When the ancients took it, it could not be purified. It had more impurities than the synthetic one, and there were many lumps. If it was not crushed, it would not be fully reacted, and it would consume more.  time.  This is equivalent to the preliminary preparation and crushing of raw materials in chemical production, which is very necessary.

    Chen Zairong was more anxious than a monkey eager to pick ripe peaches. Upon hearing this, he hurriedly put the soda ash away and ran away as fast as he could.  Wang Chen asked curiously: "Zairong, what are you going to get?"

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

    Chen Laoshi¡¯s eyes shone with approval: ¡°This is a good idea. Wasn¡¯t the soda ash in the past just crushed with a rolling pin? This kind of idea can only be thought of by Zai Rong.¡± At the end, he did not forget to praise his precious son.

    There was no suitable crushing equipment in the Tang Dynasty. Chen Wanrong had no idea about the production of the Tang Dynasty.? Not familiar enough, and just as he was thinking about how to crush soda ash, Chen Zairong had already thought about it. This kind of reaction ability is indeed superior to others, and people have to admit it.

    When Chen Zairong turned around, he not only had a rolling pin but also a round wooden board in his hand.  When Chen Laoshi saw the wooden board, it was the bottom of the barrel he used to make barrels. His face was sullen and he was very unhappy: "Zairong, what are you doing with the bottom of the barrel? Take it back quickly."

    "Dad, how can we grind it without this thing? Dad, I think the size of this thing is just right." Chen Zairong happily raised the bottom of the bucket.

    Chen Wanrong took a look and found that Chen Zairong was right. The bottom of the barrel was really suitable.  However, anything he can find is suitable. Chen Wanrong doesn't want to make Chen Laoshi feel distressed: "Zairong, don't use it. I'll find one."

    Chen Laozhen touched his forehead: "Wanrong, don't look for it anymore, just use it. Just use it. Just a little wood and a while of work?"

    ???????????????? Still a little reluctant to part with it, Mrs. Chen Wang quickly echoed: "Just wash it after using it. Old man, how distressed are you?"

    "Who said I feel distressed? Use it, use it now." Chen Laoshi was very generous to Chen Wang.

    Chen Zairong wanted to see the strange thing about stones growing in the water. He didn't care about anything. He put the bottom of the bucket on the stove, grabbed the soda ash and sprinkled it on it. He pushed the rolling pin across it and saw lumps.  The soda ash immediately breaks into small pieces, and some of the small pieces have been turned into powder.

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

    Chen Zairong found this matter new and interesting, and his interest increased greatly. He took care of it all.  He couldn't help but grab the soda ash, sprinkle it on the bottom of the bucket, and crush it with a rolling pin.

    The benefits of martial arts training were once again demonstrated. The soda ash he processed was as fine as flour, even if it was processed with a modern crushing equipment, Chen Wanrong was once again impressed by the power and wisdom of the ancients.

    The purity of natural soda ash is not very high. Eighty or ninety percent is already great. Taking the loss into account, it takes more than ten kilograms to make ten kilograms of caustic soda. Chen Zairong processed almost fifteen kilograms, which is enough for this purpose.  Then he gave up.

    Processing the soda ash took a lot of time, and it took a full half an hour to complete it.  The lime solution has settled, and a thick layer of impurities has accumulated at the bottom of the barrel.

    While Chen Zairong and Chen Wanrong were dealing with soda ash, Chen Laoshi and his wife went to wash an old wooden barrel. Chen Wanrong picked up a ladle and was about to scoop the lime solution into the old barrel. Chen Zairong, who couldn't stop himself, called  Saying "Brother, I'll come", he grabbed the ladle with his hands and scooped the solution into the old bucket.

    After scooping out the solution, it¡¯s time to add soda ash for the final chemical reaction.  Chen Zairong jumped over, brought the wooden basin containing soda ash and placed it on the edge of the bucket. He grabbed the soda ash with his right hand and opened his eyes wide, ready to watch the magical scene of "stones growing in the water".

    Looking at Chen Zairong¡¯s eager look, Chen Wanrong couldn¡¯t help but feel funny.  The modern chlor-alkali industry produces caustic soda by electrolyzing salt water to produce caustic soda. If soda ash and lime were used to produce caustic soda like Chen Wanrong, he would be short of pants because soda ash is more expensive than caustic soda.

    In the era of planned economy, some alkali plants used this method to produce caustic soda. The workers¡¯ life was quite good. Everyone knows the reason and I won¡¯t go into details.  Chen Wanrong used this method to produce caustic soda in the Tang Dynasty. Not only did he not lose money, but he also made a lot of money. It is really unpredictable!  (Remember the website address: www.hlnovel.com
