"Chemistry?"
The children exclaimed and turned to look at Qin Qi, their eyes filled with anticipation.
Teacher Qin was always able to share some new knowledge. Every time they heard new knowledge, the children would always be unable to suppress their excitement.
The snotty boy looked at Qin Qi excitedly and said,""Teacher, what is this 'chemistry?' Is it the same as the physics you taught us before?”
Qin Qi smiled and rubbed the snot baby's head. He said gently,""Of course not. Chemistry is a new field of knowledge, but everyone should have seen some chemical phenomena.”
"Have we met before?"
This time, the children were even more excited. They were so shocked that their mouths were wide open.
Chemistry sounded so mysterious that the children subconsciously thought that it was a knowledge that was far away from them. However, Qin Qi actually said that they had seen it before?
The children were all staring at Qin Qi, their faces full of curiosity. Even the old village chief could not help but perk up his ears and secretly listen to Qin Qi's lecture, wanting to know what chemistry was.
Qin Qi smiled mysteriously and did not explain. Instead, he turned to Da Niu and the others and said,""Da Niu, go and get some people to bring out those jars from my room.”
"Yes, sir!"
Da Niu and the other children tensed up and ran towards Qin Qi's study.
Qin Qi and the others were not idle either. They moved the mineral salt down from Che Shan and crushed it.
After thinking for a moment, Da Niu and the others came over with a few large ceramic jars, panting.
Qin Qi looked at the pale green liquid in the jar and smiled.
He had prepared the solutions beforehand. As long as he soaked them in this volume, he could successfully remove the toxic substances in the coarse salt and turn it into edible refined salt.
Qin Qi instructed the child to put the mineral salt into the big vat and explained,"Children, chemistry is actually the study of the most fundamental reason why everything changes.”
"Just like the mineral salt in our hands, it is poisonous because it contains substances called Xiao and phosphorous and potassium. It is these two substances that cause poisoning. However, as long as these two substances are removed, the mineral salt can become edible refined salt.”
The child Meng nodded his head in a half-understanding manner. The old village chief looked at the mineral salt in his hand in horror, and a huge wave rolled up in his heart.
It was common knowledge that mineral salt was poisonous and would kill people if they ate it. However, Qin Qi actually said that he could turn mineral salt into expensive table salt.
Was that even possible?
Da Niu turned around and pointed at the liquid in the vat. He raised his hand and asked,""Teacher, can these things turn mineral salt into table salt?”
Qin Qi smiled and patted his head.""That's right. This is a solution of soda that my teacher specially prepared. They will have a magical chemical reaction with the salt in the vat, and then the impurities in the salt will be removed.”
"It's okay if you don't understand now. I'll teach you in detail in the future. In today's class, I want you to understand one thing-the most important thing in chemistry is experimentation.”
The children listened to Qin Qi's explanation meticulously. Their hands did not stop moving. They threw the salt blocks in their hands into the jars one after another. There were even children who secretly took branches from the ground to record the contents of Qin Qi's explanation.
Although they still could not understand what Qin Qi was talking about, it did not affect their curiosity at all.
These children were like a sponge, absorbing the knowledge taught by Qin Qi hungrily.
......
Qin Qi smiled as he looked at the reaction between the salt and the solution.
Not bad, the experiment was a success. Now, all they had to do was wait for the results!
Qin Qi turned around and looked at the curious children. He smiled and patted the snotty boy's head."Children, it will take seven days to purify the refined salt. From tomorrow onwards, I will officially teach you chemistry!”
"When you learn how to refine coarse salt, when you grow up, you can become officials in the court and teach the people of the country how to refine salt so that everyone in the Great Tang can eat salt!”
The children nodded vigorously, their faces filled with desire. Qin Qi's words had planted a seed in their hearts. When these children grew up, this seed would take root and sprout. Under the leadership of these children, the Great Tang would become even stronger!
The old village chief looked at Qin Qi with admiration. Not only did Mr. Qin teach these children knowledge, but he also pointed out the future path for these children!
His heart had never been filled with a small Great Liang Village, but the entire Great Tang!
This was a true saint!
Qin Qi looked at the children with a smile and did not say anything. He just turned to look at the prosperous Chang 'an City in the distance, and a gleam of light flashed in his eyes.
Extracting refined salt was only the first step of his plan. In the future, he would have more advanced results. Whether it was high-yield rice or cotton that could keep people warm, they were all his future research directions!
Since he had come to this world, he didn't just want the children of the Great Tang to use knowledge to change their fates.
He wanted to use the knowledge in his head to change the fate of the Great Tang!
