I was watching short videos and was seen by ancient people

Chapter 255 Necessary for Time Travel—Sulfuric Acid ()

"Wait a minute: Even if Xiang Shaolong watches your video, the receiver will not run out of power~~~"

When people from various dynasties saw the comments on the marquee, they were a little curious as to why the marquee said so, and who was Xiang Shaolong?

At the same time, they are also very curious, what is electricity? It is so important to future generations.

Although they don't understand what "electricity" is? But they secretly remembered it in their hearts.

After all, these things that are so important for future generations can definitely be widely used in their era.

It's just a pity for them that there is no introduction on how to create "electricity" on the marquee.

"Enthusiastic Citizen: The cylinder tower method used by the Chinese army at that time was to stack two clean and undamaged cylinders face to face and seal them tightly to form a reaction tower. Remember that there are twenty-two cylinders in one reaction tower and they can be ignited with sulfur. [look]. 》

People from all dynasties were very happy when they saw the comments on the sky screen.

At this time, it was not easy for them to find a truly airtight container.

When they saw that making sulfuric acid on the canopy required sealed containers, they felt that they did not have the conditions to make it.

And the method mentioned in the Tianmu comment section is simply prepared for them.

This is not only simple, but also allows them to make it under existing conditions.

So people from all dynasties began to take action and began to make sulfuric acid.

This is something they don't know, and the danger will come with them.

"The fragrance of flowers fills your clothes: For fertilizer, nitric acid or phosphoric acid is better [Secret observation]. 》

what?

Can these acids be used as fertilizer?

Countless people in various dynasties couldn't believe that these acids could actually be used to make fertilizer!

You must know that for them, fertilizer has always been fermented from straw and manure in the land.

They also don't understand. Is the fertilizer made in this way useful?

But thinking about the crop yields in later generations, they dispelled their doubts.

At the same time, they began formulating plans to study how to use these acids to make fertilizers.

But before they started taking action, they saw the following comment.

"Southern Little Potatoes: It is easier to use three strong acids to make sulfuric acid: heating ferrous sulfate, which is green vitriol, to obtain sulfuric acid with low purity. The second type requires electricity to produce sulfuric acid, which is electrolysis of copper sulfate.

Hydrochloric acid: Add salt to more than 95% concentrated sulfuric acid to generate hydrogen chloride gas and react with water. 》

Nitric acid: The first one requires electricity, and uses a high-voltage arc to force oxygen and nitrogen to react to generate nitrogen dioxide. The aqueous solution of nitrogen dioxide is nitric acid.

The second option is to wait for a year, take a ceramic urinal, put plant ash and animal excrement in it, and store it in the soil. After a year, there will be nitric acid. 》

People from all dynasties were shocked when they saw the comments on the canopy and the manufacturing methods of the three powerful acids described on the canopy.

They did not expect that this time they were not only introduced how to make sulfuric acid, but also taught them how to make other acids in the comment area.

And not only gave them more difficult methods, but also taught them simpler methods.

Some people took action and took out the "green vitriol oil" they obtained and started making hydrochloric acid.

Some people began to make nitric acid. For them, they did not understand the first method of making nitric acid, and they did not know how to do it.

But the second method is much simpler and can be produced under their conditions. After all, the nitric acid material produced by the second method can be obtained nearby, unlike the first method, which they cannot even understand.

At the same time, they were also waiting, waiting for the marquee to introduce the specific functions of hydrochloric acid and nitric acid, so that they could sell the things they made.

They believe that what they make based on the prompts on the marquee will definitely change their lives.

At this moment, new comments appeared on the sky screen.

"Qilixiang: Three acids include sulfuric acid, nitric acid and hydrochloric acid. Each of them has a wide range of applications and is also the mother of the foundation of industry.

Sulfuric acid: Sulfuric acid is widely used in metal processing, mineral extraction and manufacturing. It can be used to clean and deoxidize metal surfaces, as well as in processes such as electroplating, electrolysis and corrosion treatments. In addition, sulfuric acid can also act as a catalyst to promote certain chemical reactions.

Nitric acid: Nitric acid is mainly used for cleaning and corrosion of metal surfaces. It is a strong oxidizing agent and can be used to make explosives and fertilizers. In the electronics industry, nitric acid is used in batteries, ultrasonic cleaning and the production of electronic components.

Hydrochloric acid: Hydrochloric acid is used in waste disposal, electroplating, household cleaning and manufacturing. It is a strong acid that removes stains and corrosion from metal surfaces. In addition, hydrochloric acid is used in water treatment, textile dyeing and pharmaceutical industries.

Please note that although these acids have a wide range of applications, they are strong acids and are highly corrosive and appropriate safety precautions should be taken when handling and using them. 》

People from all dynasties were very happy when they saw the new comments.

Although they did not understand some of the content of this comment on the marquee, they still found the direction of their use in it.

In particular, the canopy reminded them that this was also highly corrosive and asked them to take appropriate safety measures.

If it hadn't been for the prompt on the sky screen, I'm afraid they would have acted recklessly.

Especially after some people made gunpowder, they understood the function of the prompts on the canopy.

At the same time, when they saw the effect of nitric acid, they were even more surprised.

So they started taking action and kept experimenting to find out how to make the fertilizer.

Qin Dynasty.

When Qin Shihuang saw the comments on the Tianmu, he was very happy. He felt that he had learned some new knowledge on the Tianmu.

Ever since the canopy appeared in the sky, Da Qin has been learning new things on the canopy, and the Mohist disciples have also made many things based on the information on the canopy.

For them, Great Qin, the four major inventions are more important.

Whether it was papermaking or printing, Da Qin had made a qualitative leap.

And now the technology mentioned on the canopy is more about making Da Qin even better on the original basis.

But even so, Qin Shihuang hopes that everyone can learn more and more things.

This kind of Great Qin will gradually become stronger, and the lives of those people will become better and better.

What impressed him deeply was that after learning how to make gunpowder on Tianmu and applying gunpowder to the battlefield, those Huns did not dare to step into the Qin Dynasty.

They thought that the gods were angry and that their violations would be repaid.

Not only that, but bombs made of gunpowder can also scare the horses of the Huns, making them no longer mobile. Wouldn't this be an advantage to Da Qin?
