Chapter 164: Acid Production
Kemo Stoll had barely slept in these days, and he found that coming to Frontier was the best choice he had ever made in his life.
It took two days and one night to read all the "Elementary Chemistry", and after sleeping for two or three hours, I was full of energy again. Now he had returned to the first page and was studying the ancient book again.
Matter is made up of very small particles! The change of matter is the decomposition and reorganization of particles! During the reaction, the total amount of matter remains the same!
God, what kind of characters are the authors of this book who can depict the world so clearly that people can't see. He had suspected more than once that the contents of the book were all made up, but the results of the alchemical experiments according to the above examples were completely consistent! Moreover, some common examples in reality can also prove the correctness of the book.
For example, "oxygen" described in Chapter 1.
This gas is the main component of air, and people do not breathe air, but oxygen. Oxygen is required for flame combustion because combustion is essentially an oxidative reaction. The more oxygen, the more vigorous the combustion.
These words reminded him of the glass kiln in Chishui City, where it took two people to keep shaking the blower bag to make the temperature in the furnace rise to the melting point of sand and stone. Since it is a substance, it can obviously also pass through alchemy...... No, pure oxygen is extracted through a chemical reaction. If oxygen can be directly injected into the furnace, can the blower equipment be saved?
And the most amazing thing is that the book says that water is actually composed of two hydrogen particles and one oxygen particle, which is probably the reason why all living beings drink water. But hydrogen also seems to be a gas, and the two gases come together to become a liquid, how does this happen?
Kemo found himself with many questions to ponder. But there was no doubt that he was already ahead of all the alchemists, and while they were still groping for formulas in chaos and fog, a straight and flat avenue appeared in front of him.
However, business still has to be done. He reluctantly closed the book. By this time, the sky had turned white, and it was time to work again.
Kemo blew out the candles, approached the bedroom to look at his sleeping wife and daughter, and quietly went out.
The residence that His Highness had assigned to him was located to the west of the castle, much larger than his home in Chishui City, with walls made of masonry and stone, which was obviously much more comfortable than the moldy wood, and was well equipped with furniture and kitchen utensils. Although he didn't say it, he felt more satisfied in his heart. The disciples lived in a small neighborhood two blocks away from him, and the house was smaller and not a separate house, but rather a hotel, with a bedroom for four people.
Walking to the chemistry laboratory by the Chishui River, the disciples were already busy. They were carefully selected by Kemo, who had been learning to clean materials in the alchemy workshop almost as children, and were now between twenty and thirty years old. Seeing the cleanly cleaned laboratories and shiny glass containers, Kemo nodded in satisfaction.
"Good morning, Master Teacher," the disciples bowed their heads and saluted.
"Let's get started. He took out a pair of gloves from the cabinet and put them onโthey were extremely thin and elastic, presumably sewn together from animal intestines. There had never been such a rule in the alchemy workshop before, but His Royal Highness the Prince repeatedly stressed the danger of chemical experiments, and in the operating regulations, all those involved in the reaction of corrosive raw materials must wear gloves and open all windows at the same time.
Unlike the Workshop, their job now is very clear, which is to make acid for His Highness. They have already operated the method of making acid from two stones, so Kaimo only needs to patrol and guide on the sidelines, and does not have to go down to the field himself.
Both of these acids are well documented in the Elementary Chemistry, one is called sulfuric acid and the other is nitric acid. He used to name it after the manufacture, for example, the former was called alum acid, and the latter was called saltpeteric acid. The name is different, the preparation method is basically the same, the acid vapor is obtained by dry distillation of alum and saltpeter, and then the acid is collected by condensation. Alum is usually associated with sulfur ore, and saltpeter is produced in large cities in special nitrate ponds, both of which are common raw materials.
However, His Royal Highness emphasized that the concentration of the two acids he wanted must be high, and he also specially explained the purification method.
For example, after the sulfuric acid is collected, the water can be evaporated through heating, and finally the concentrated sulfuric acid with a concentration of up to 90% can be obtained. However, nitric acid is a lot more troublesome, listening to His Royal Highness the Prince, this acid itself is not very stable, easy to volatilize, and after the concentration is high to a certain extent, it will decompose even when it sees light. Therefore, the dilute nitric acid from dry distillation must be mixed with concentrated sulfuric acid and heated to allow the concentrated sulfuric acid to absorb water, evaporate the nitric acid, and store it in a brown glass bottle. For this reason, His Highness also specially prepared a thermometer.
The first time Kemo saw it, he thought it was ingenious, a hollow glass tube containing mercury, and both ends were sealed, so he didn't have to worry about the mercury leaking out. There are several circles of lacquer lines drawn on it, and the mercury will gradually rise as it is heated, and the final position represents the current temperature.
Today, the lab has produced three bottles of concentrated sulfuric acid and one bottle of concentrated nitric acid. At this concentration, he discovered that sulfuric acid was not as easy to flow as water, but more like a somewhat viscous oil. At high concentrations, nitric acid is no longer colorless and transparent, but has turned pale yellow, and as long as the glass cap is opened, it will emit bursts of white smoke.
"Master, do we have to make these two acids every day?" asked a disciple named Amun.
"Until His Highness gives a new task. Kaimo paused, "What's the matter, I'm worried that I don't have time to fumble for the alchemy formula?"
Amon nodded.
Kaimo touched the stubble on his chin and smiled, "I forgot to tell you, the title of alchemist will not be needed in the future, so you don't have to rely on groping for formulas to become alchemists." โ
"No......" Amon was stunned, "Don't need it?" The other disciples also slowed down their work and listened intently to what the master wanted next.
"That's right, the alchemy formula doesn't need to be groped anymore, but memorized and deduced," Kaimo clapped his hands and simply gathered everyone around him, "Your Highness has given me a copy of Elementary Chemistry - that's why I brought you here, if you study it thoroughly, most of the formulas in the world can be guessed from the contents of the book." โ
"Speculative?" the disciples let out a low cry.
"That's right. After I have read it in detail, I will start teaching it to you. He said, "As for the path of promotion, His Highness also mentioned it to me. In the future, you will have to pass a test that he personally arranged in order to be awarded the title of chemist. Believe me, it won't be long before this honorary title will completely override the alchemist. And the knowledge you have is beyond even the reach of the Royal Alchemy Association.
