Release that Witch

Camo Spoel has hardly slept in these days, and he found that Bentham Town is the most correct choice he has ever made in his life.

After spending two days and one night, I turned "Primary Chemistry" all over again. After sleeping for two or three hours, I was full of energy. Now that he has returned to the first page, he has carefully studied this ancient book.

The substance is made up of tiny particles! The change of matter is the decomposition and reorganization of particles! During the reaction, the total amount of the substance does not change!

God, what the writers of this book are, can actually portray the world that people cannot see so clearly. He has repeatedly suspected that the contents of the book are all made up, but according to the above example, the alchemy test, the results are fully in line! Moreover, some examples that are common 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. People breathe not air but oxygen. Oxygen is required for flame combustion because combustion is essentially an oxidation reaction. The more oxygen, the more vigorous the combustion.

These words reminded him of the glass kiln in Chishui City. Two people were required to keep shaking the blast sac in order to raise the temperature inside the furnace to the melting point of the sand. Since it is a substance, it is obvious that it can also pass through alchemy... No, pure oxygen is extracted by chemical reaction. If you can directly pass oxygen to the furnace, can you save the blast equipment?

And the most amazing thing is that the book says that the water is actually composed of two hydrogen particles and one oxygen particle, which is probably the reason why all things need to drink water. But hydrogen seems to be a gas. The two gases combine to become a liquid. How do you do this?

Kemo found that he still had a lot of problems to ponder. However, there is no doubt that he has walked in front of all the alchemists. When they are still exploring the formula in chaos and fog, there is a straight and flat road in front of their eyes.

However, the business is still going to be done. He reluctantly closed the book. At this time, the horizon has gradually become white, and it has reached the time of work.

Kemo blows out the candle, walks close to the bedroom and looks at the sleeping wife and daughter, and quietly leaves the door.

The house assigned to him by His Highness is located west of the castle, much larger than his home in Chishui City. The walls are made of masonry. This house is obviously much more comfortable than the wood that is easy to mold, and the furniture and Kitchenware is readily available. Although he did not say anything in his mouth, he felt more satisfied in his heart. The disciples lived in another neighborhood two blocks away from him. The house was smaller and not a separate house. It was a bit like a hotel setting, and one bedroom could accommodate four people.

Walking to the chemical laboratory near the Chishui River, the disciples are already busy. They are carefully selected by Caimo, who have been studying cleaning materials in alchemists since childhood, and are now between the ages of 20 and 30. When he saw the cleaned laboratory and the sparkling glass container, Kemo nodded with satisfaction.

"Good morning, the chief instructor," the disciples bowed their heads together.

"Get started." He took a pair of gloves from the cupboard - the gloves were extremely thin and flexible, probably stitched with animal intestines. Previously, there was no such rule in the alchemy workshop, but His Royal Highness repeatedly emphasized the dangers of chemical experiments. In the operating regulations, all the windows involved in the reaction of corrosive materials must wear gloves and open all windows.

Different from the workshop, the content of their work is very clear now, that is, to prepare acid for the temple. The method of double stone sulphur has been operated many times, so Kaimo only needs to patrol the side and do not have to start the game in person.

These two acids are well documented in Elementary Chemistry, one called sulfuric acid and the other called nitric acid. He used to be named after the manufacturer, such as the former called citrate, the latter called nitrate. The name is different, the preparation method is basically the same, the acid vapor is obtained by retorting the vermiculite and the saltpeter, and then the acid solution is collected by condensation. Green carp is usually associated with sulphur ore, and saltpeter is produced in a special septic tank in large cities, which are common raw materials.

However, His Royal Highness emphasized that the two acid concentrations he wanted must be high, and he also specifically explained the purification method.

For example, after the sulfuric acid is collected, the water can be evaporated by heating to finally obtain concentrated sulfuric acid having a concentration of up to 98%. However, nitric acid is a lot of trouble. Listen to the prince, the acid itself is not stable, it is easy to volatilize. After the concentration is high to a certain extent, even the light will decompose. Therefore, the distilled dilute nitric acid must be mixed with concentrated sulfuric acid and heated to allow the concentrated sulfuric acid to absorb water, and the nitric acid is evaporated and stored in a brown glass bottle. To this end, His Royal Highness also specially prepared a thermometer.

When Kemo saw it at first sight, he felt that this thing was really exquisite. A hollow glass tube contained mercury and both sides were sealed. Don't worry about the mercury leaking out. There are a few lines of paint on the top, and the mercury will gradually rise when heated, and the final position will represent the current temperature.

Today, the laboratory has produced three bottles of concentrated sulfuric acid and a bottle of concentrated nitric acid. At this concentration, he discovered that sulfuric acid is not as easy to flow as water, but rather a somewhat viscous oil. Nitric acid is no longer colorless and transparent at high concentrations, but becomes pale yellow. As long as the glass bottle cap is opened, white smoke will be emitted.

"Instructor, do we have to make these two acids every day?" asked a disciple named Amon.

"Until the Highness is down to the new mission." Cameron paused. "What's wrong, worrying about not having time to explore the alchemy formula?"

Amon nodded.

Kemo smiled at the chin that touched his chin. "I forgot to tell you that the title of the alchemist is not needed anymore, so you don't have to rely on the formula to become an alchemist."

"No..." Amon stunned. "No need?" The other disciples also slowed down the work at hand and listened to what the mentor wanted next.

"Yes, the alchemy formula does not need to rely on groping, but memory and deduction," Camo clap his hands and gather everyone together. "His Royal gave me a copy of "Primary Chemistry" - this is also my belt. The reason why you come here is that if you study thoroughly, most of the formulas in the world can be inferred from the contents of the book."

"Put it out?" The disciples made a low cry.

"Yes. After I read it in detail, I will teach you the course." He said, "As for the promotion path, my Highness has also mentioned it to me. In the future, you must pass the test he personally arranged to get the title of chemist. I, no matter how long, this honorary title will be completely above the alchemist. And the knowledge you have, even the Wangdu Alchemy Association is far behind."
