"Ahem! Mountain Chief, there's a mess in this house, don't mind! Here's everything you need to have! Look! This is the beaker you mentioned in the textbook "Chemistry", this is the graduated cylinder, this is ...."

In a room in the office building of the workshop, Wang Ji introduced the experimental equipment in the room to Li Zexuan with a few treasures, in fact, where he needs to be introduced, Li Zexuan himself knows better than anyone else!

Paying close attention to Wang Ji's tone, it can be found that when it comes to matters related to "Chemistry", his attitude towards Li Zexuan has become respectful, because in learning, he has always been a master as a teacher! Li Zexuan is better than him in this aspect, that's a fact!

"Hmmm! Very good! It can be seen that Mr. Wang has really bothered in recent days! ”

Li Zexuan scanned the experimental equipment in the room and nodded in admiration.

When Wang Ji heard this, he immediately grinned, "Hey! In the final analysis, this workshop is better built by you, the mountain chief! Without the help of those craftsmen, no matter how capable he was, he would not have been able to make so many things in such a short time! ”

What he said is really right, if you want to talk about the credit here, it must be Li Zexuan's greatest credit, if he hadn't invented the method of firing colored glass, Wang Ji wouldn't have been able to make any of these experimental instruments in front of him!

"Huh! Mr. Wang is too humble! ”

Li Zexuan laughed, and then asked, "Has Mr. Wang been living in this house these days?" ”

For he saw a very simple wooden bed in the corner of the opposite wall. Thinking of this cold day, the old guy in front of him, who was nearly half a hundred years old, was actually experimenting inside day and night, Li Zexuan felt a little sad!

This is not how "scientists" should be treated!

But this is really Wang Ji's consistent style of life!

When Yanhuang Academy was first established and the first batch of teachers were recruited, Wang Ji studied the "Chemistry" textbook for nearly a month day and night in order to win the bet with Yan Silu and prove that he was worthy of the "high salary" of the academy and the position of the subject leader of the Chemistry Department, and finally won the bet with a perfect score and proved his strength! As a result, after the exam, the old guy fell asleep directly for a day and a night!

It can be seen that this is a stubborn old man, and at the same time a very powerful old man!

This old man is so cruel to himself sometimes!

"Ugh! It's nothing, as long as there is a place to lie down, it is the same wherever you sleep! Mountain chief, you don't have to worry about the old man! ”

Wang Ji only wanted to show Li Zexuan his research results at this time, and he didn't care about his life situation at all.

Li Zexuan said categorically: "No! The body is the leather... The body is the capital of learning! Mr. Wang, you are like this now, in a few days, you will definitely get sick! I'll ask Fauber to send someone to heat up your room in a moment! ”

"Heating? What is Heating? ”

Wang Ji, who only had various chemical equations in his eyes, obviously didn't notice that the workshop had recently produced several sets of heating equipment, so he asked suspiciously.

"Let's not talk about this first, when the time comes, Mr. Wang, you will understand!"

Li Zexuan waved his hand, and then got to the point: "Mr. Wang, you just said outside that you recently discovered a new thing, what is it that makes you so happy~?" ”

Wang Ji immediately became in high spirits at this time, he walked quickly to the experimental table, took a small glass bottle with a label from it, and there was half a bottle of colorless liquid in it, and then he smiled and took the glass bottle to Li Zexuan's side, and said, "Mountain Chief, this is it!" ”

"What is this ......?"

Li Zexuan took it suspiciously with one hand, and subconsciously asked, but before he finished asking, he had already seen the H2SO4 label on the bottle, and the doubt on his face suddenly turned into surprise: "Sulfur... Sulphuric acid? ”

Wang Ji nodded quite smugly, and said, "Hmm! That's right! It's sulfuric acid! ”

Old man Wang has painstakingly studied the textbook "Chemistry", Li Zexuan is not surprised why the old guy can say the name sulfuric acid, but now Wang Ji actually swears that he made sulfuric acid, which makes Li Zexuan very unbelievable, "Mr. Wang, how did you make sulfuric acid?" ”

The basis of the modern chemical industry is "three acids and two alkalis", and it can be said that without "three acids and two alkalis", there would be no modern chemical industry! And sulfuric acid is one of the important members of "three acids and two alkalis", if Wang Ji really created sulfuric acid, it would be really amazing!

(The "three acids" are sulfuric acid, hydrochloric acid, and nitric acid, and the "two bases" are sodium hydroxide and sodium carbonate)

Wang Ji took out a small box from the drawer, and took out a small paper bag from the wooden box, the paper bag opened, revealing a small pinch of green powdery objects inside, then Wang Ji smiled:

"Mountain chief, this is it! The old man put the green alum on the flame and burned it, and found that it would produce a gas, and this gas can be well dissolved in water, after the old man used the chemical equation to calculate, this solution is likely to be sulfuric acid! ”

Copperas!!

Isn't this thing a hydrous crystal of ferrous sulfate?

Li Zexuan was stunned for a moment, and suddenly remembered that according to the chemistry books in his previous life, it is indeed possible to produce dilute sulfuric acid in small quantities by burning alum, the chemical equation: 2FeSO4·7H2O = (high temperature) Fe2O3 + SO2 + SO3 + 14H2O, sulfur trioxide dissolved in water is dilute sulfuric acid. It's just that Wang Ji, where did he get the green alum?

"Mr. Wang......"

With doubts in his heart, Li Zexuan just wanted to ask Wang Ji where he got the green alum? Suddenly, the memory of the predecessor in his mind made him wake up again, it turned out that green alum was a kind of traditional Chinese medicine in ancient times, and Wang Ji must have come from Sun Simiao!

There are records of the medicinal use of green alum in the "Tang Materia Medica" and the "Compendium of Materia Medica", which can treat typhoid, malaria and other diseases.

"Hehe, you guessed right, mountain chief! This green alum was borrowed by the old man from Doctor Sun! ”

Wang Ji seemed to have seen through Li Zexuan's thoughts, and said with a smile.

As for the "borrowing" in his mouth, it must be borrowed but not returned! Sun Simiao reacted after a while, and it was estimated that he would have to trouble Wang Ji!

"Huh! Mr. Wang is truly talented! I can actually think of using green alum to make sulfuric acid, admire and admire! ”

Li Zexuan was convinced.

This chemical reaction may not be difficult for him, a modern person, but Wang Ji, an ancient person, was able to produce dilute sulfuric acid by slowly pondering by himself, which is really remarkable! At all times, it's much harder to create than to innovate!

Wang Ji smiled and said, "Where, where!" This is all the inspiration that your "Chemistry" textbook has given to the old man! Besides, some of the old man's early experiences have also brought a lot of help! ”
