Release that Witch

164. Chapter 164 Acid Production

    Cam Schuire For several days, he barely slept, and he found that Border Town was the right choice for his life.

    It took two days and nights to turn all the «Elementary Chemistry» over and over again. After two or three hours of sleep, it 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 qualitative change is the decomposition and reorganization of particles! During the reaction, the total amount of the substance remains the same!

    God, what the writers of this book are, can actually portray the world that people can’t 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, the “oxygen” described in the first chapter.

    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 stronger the burning.

    These words reminded him of the glass kiln of Scarlet Water City, which required two people to keep shaking the blast sac in order to raise the temperature inside the furnace to the Melting Point of the gravel. Since it is a substance, it is obviously also possible to pass 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 water is 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?

    Cam found that he still had a lot of questions to ponder. However, there is no doubt that he has walked in front of all 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 still has 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.

    Cam 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 Royal Highness is located west of the castle, much larger than his home in Scarlet Water City. The walls are made of brick stone steps, which are obviously much more comfortable and furniture than the moldy wood. It is fully equipped with kitchenware. 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 lab at the side of Scarlet Water River, the disciples are already busy. They are carefully selected by Cam, who have been learning cleaning materials almost at the alchemical workshop since childhood, and are now between the ages of 20 and 30. Seeing the cleaned laboratory and the sparkling glass container, Cam nodded with satisfaction.

    “Good morning, the chief tutor,” the disciples bowed their heads together.

    “Get Started!”He took a pair of gloves from the cupboard – the gloves were extremely thin and flexible, presumably stitched with animal intestines. Previously, there was no such regulation in the alchemical 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.

    Unlike the workshop, the content of their work is now very clear, that is, to prepare acid for the temple. The method of double stone sulphur has been operated many times, so the Cam 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 known as green citrate, the latter known as saltpeter acid. 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 collecting the acid by condensation. Green carp is usually associated with sulphur ore, and saltpeter has 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, even the light will be decomposed. Therefore, the distilled dilute nitric acid must be mixed with concentrated sulfuric acid and heated to allow 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.

    Cam saw it at first sight and thought it was awesome. 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 cap is opened, white smoke will be emitted.

    “Instructor, do we have to get these two acids every day?”A disciple named Amon asked.

    “Until His Highness explains the new task.”Cam paused, “What’s wrong, worry about not having time to explore the alchemy formula?”

    Amon nodded.

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

    “No!Amon stunned, “No need?”Other disciples also slowed down the work at hand and listened to what the instructor wanted next.

    “Yes, the alchemy formula doesn’t need to be groping, but memory and Derivation,” Cam clap his hands and gather everyone together. “His Royal gave me a «Elementary Chemistry» – this is also my The reason why you come here, if you study thoroughly, most of the formulas in the world can be inferred from the contents of the book.”

    “Inferred?”The disciples made a low cry.

    “That’s right. After I have 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. Believe me, no matter how long, this honorary title will be completely above alchemist. And the knowledge you have, even the Kingdom Capital Alchemy Association is far behind. ”
