Live streaming life: The ancients begged not to stop

Chapter 246

After Qi Cheng returned home, he moved all his things upstairs, then lay on the sofa and played with his mobile phone. As soon as he turned on the mobile phone, it pushed the necessary skills for time travel to him.

And this skill is quite powerful.

[Once your power is completely consolidated, you'll need to develop industry. For example, to increase the power of firearms, you'll need to develop some chemistry.]

The basis of chemical technology is three acids and two bases.

Being able to produce something is one thing, being able to produce it on a large scale is another. It was also very difficult for my country to produce these things in the beginning.

Daqin

Can it increase the power of firearms? Qin Shi Huang shouted, asking the waiter to quickly bring paper and pen. The Qin Dynasty had already produced artillery, and its power was quite good.

The Huns were frightened and did not move south for a long time.

This three acids and two bases method is so powerful, Daqin must learn it.

Tang Dynasty

Li Shimin instinctively felt that this was basic knowledge, and the chemistry that Tianmu mentioned should also be a very powerful subject, and he had to find suitable students to study hard.

This is an opportunity!

Let's first talk about what the three acids and two bases are. The three acids refer to sulfuric acid, nitric acid, and hydrochloric acid, and the two bases refer to soda ash, sodium carbonate, and caustic soda, sodium hydroxide.

Let's first talk about the three acids. Sulfuric acid has been produced in ancient times, usually by calcining green vitriol. However, this method produces toxic gases and has a relatively low yield.

We currently use the sulfur combustion method. Sulfur combustion produces sulfur dioxide, which dissolves in water to form sulfurous acid. This is then slowly oxidized to sulfuric acid in the air. Using concentrated sulfuric acid to absorb sulfur trioxide can produce purer sulfuric acid.

Great Sui

Yang Jian felt a headache when listening to what Tianmu said. He was confused by all the acid and sulfur, and he doubted whether this thing could really be made.

He felt that the Sui Dynasty did not have the strength to do so, and other dynasties would probably be in trouble too.

Song Dynasty

Several interested officials got together and thought they could learn this thing. They even arranged for their servants to buy sulfur.

"This writing is easy to understand, but I think those letters are the most mysterious. It would be great if I could learn them all."

"I've already guessed part of the content. The rest I can only ask the host when the time comes."

"Can he know?"

“These should be the basics.”

……

Next, let's talk about how to make hydrochloric acid. It's actually very simple. Just add table salt to concentrated sulfuric acid to produce hydrogen sulfide gas.

【When dissolved in water, it becomes hydrochloric acid. 】

[In this experiment, pay attention to the speed and gas collection. These chemicals are still very dangerous. Don't try it unless you are fully familiar with them. (Don't try it in real life either, it's dangerous.)]

Nitric acid can be produced by dry distillation of saltpeter. We've already discussed saltpeter, so I won't go into details here. Dry distillation of saltpeter produces oxygen and potassium nitrite. Potassium nitrite further decomposes to produce nitrogen oxide and potassium oxide. The nitrogen oxide then reacts with oxygen in the air to produce nitrogen dioxide.

Nitrogen dioxide dissolves in water to produce nitric acid.

[This process is rather troublesome and requires some professional equipment support.]

This process is no longer a hassle. Many people outside the sky who are determined to study have fallen behind. This is too difficult for them, and they plan to ask if there is a simpler way.

However, a few Taoists understood what was said, and they planned to try to see if they could use the three acids to refine new elixirs.

Even if it can't make you immortal, it can have other uses.

Sulfuric acid has a wide range of applications. It can dissolve ores, is used in batteries, and can also be used to produce fertilizers.

[For example, phosphate fertilizer is made from phosphate rock sulfate to produce phosphoric acid, which is then used to make phosphate fertilizer.]

【Hydrochloric acid is an important condition for the production of various organic compounds.】

[Nitric acid can be made into nitrocellulose and nitroglycerin, both of which are more powerful than gunpowder.]

big man

When Liu Che heard that it was more powerful than gunpowder, he immediately became excited. The Han Dynasty was in need of such a thing. Previously, the Shaofu had done a great job in making the musket.

But the power is average.

If he could make the things that Tianmu mentioned, he would be able to suppress the Huns.

"Are you sure about the Shaofu?"

The Shaofu Ling glanced at Liu Che above and whispered that these things were too difficult. They had to experiment bit by bit and the specific results had to be seen.

And they don't have any suitable talents here.

"The Han Dynasty is vast, and there must be many talented people. If you look around, you will definitely be able to find someone who understands it."

Ming Dynasty

Zhu Yuanzhang was very concerned about fertilizers that could increase grain production. He immediately arranged for the Ministry of Industry to conduct experiments and produce some simple fertilizers as soon as possible.

"Prince, Fourth Brother, what do you think about this matter?"

Zhu Biao stepped forward and said, "Father, even if this fertilizer can be produced, it will certainly be very expensive. Ordinary people will definitely not be able to afford it."

Zhu Yuanzhang nodded.

"I think it's better to use the loan method. First, lend out the fertilizer and then charge for it after the autumn harvest..."

Zhu Di didn't think too much about the use of chemical fertilizers, but he felt that he should first fully understand the technology involved, otherwise, if he relied solely on manual operation, the output would probably not increase at all.

The production methods of the two alkalis then appeared on the screen, with emphasis on the Hou alkali production method, which was invented by us under great pressure.

It laid the foundation for the country's industrial development.

……

After the video was over, Qi Cheng thought about it and sent a few more messages to the girl. Judging from the girl's reply, there was still some hope.

If there is any hope, Qi Cheng will of course try his best.

The two chatted for about half an hour. Qi Cheng went downstairs and went to the supermarket for a stroll. He brought back some radishes and cabbages from home today, but he couldn't just eat these things.

Meat and fruit are also needed.

The people outside the sky curtain were envious again. The video played before the sky curtain was like a heavenly book to them, and they couldn't understand even a single word.

It’s better to buy things by watching the anchor.

"When can we live such a good life?"

"Can you figure out what the essential skills for time travel are that the sky curtain showed today? If you can, the court will give you a huge reward."

"Who did you listen to?"

"My second aunt's third cousin's neighbor works in the Ministry of Finance. I think the recruitment notice will be posted tomorrow."

Of course, the two people who were talking didn't understand, but the eyes of a Taoist priest next to them lit up, thinking that maybe he could make a living by eating.
