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

When the people of various dynasties saw the comments on the canopy, they were a little curious about why the canopy said this, and who was that Xiang Shaolong?

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

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

After all, these things that are so important in the future will definitely be able to be used in large numbers in their time.

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

"Enthusiastic Citizens: The cylinder tower method of my country's army back then, stacked up mouth-to-mouth with clean and undamaged cylinders in groups of two, sealed well, is a reaction tower, remember that there are twenty-two cylinders in a reaction tower, and you can ignite it with sulfur [look]. 》

The people of all dynasties were very happy when they saw the comments on the canopy.

At this time, it is not easy for them to find a truly sealed container.

When they saw that the canopy was making sulfuric acid and needed a sealed container, they felt that they were not in a position to make it.

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

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

So the people of various dynasties began to act and began to make the sulfuric acid.

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

"Flowers are full of fragrance: nitric acid or phosphoric acid is better as fertilizer. 》

What?

Can these acids be used as fertilizers?

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

You must know that for them, fertilizer has always been made by fermenting straw and manure in the ground.

They also don't understand, is the fertilizer made in this way useful?

But when they think about the yield of crops in later generations, they dispelled their doubts.

At the same time, they began to develop plans to study how to make fertilizer from these acids.

It's just that they haven't even started to act when they see this comment below.

"Southern Small Potato: Three strong acids that are easier to make sulfuric acid: heating ferrous sulfate, that is, green alum to obtain sulfuric acid with low purity, and the second kind can only be done with electricity, electrolytic copper sulfate.

Hydrochloric acid: more than 95% concentrated sulfuric acid is salted to produce hydrogen chloride gas and react with water. 》

Nitric acid: The first one requires electricity, using a high-voltage arc to forcibly let oxygen and nitrogen react to produce nitrogen dioxide, and the aqueous solution of nitrogen dioxide is nitric acid.

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

The people of various dynasties were stunned when they saw the comments on the canopy and the manufacturing methods of the three strong acids mentioned on the canopy.

They didn't expect that this time not only introduced how to make sulfuric acid, but also taught them how to make other acids in the comment section.

And not only did he give them the more difficult methods, but he also taught them the easier ones.

Some people began to take action, taking out the "alum oil" they got and starting to make hydrochloric acid.

Some people started to make nitric acid, and for them, the first way to make nitric acid was that they didn't understand and didn't know how to do it.

The second method is much simpler, and can be made on their terms.

After all, the nitric acid material made by the second method can be taken from the nearest source, unlike the first method, which they can't understand.

At the same time, they were waiting, waiting for the canopy to introduce the specific effects of hydrochloric acid and nitric acid, so that they could also sell what they had made.

They believe that something made based on the prompts on the canopy will definitely change their lives.

It was at this moment that a new comment appeared on the canopy.

"Qilixiang: Triacids include sulfuric acid, nitric acid and hydrochloric acid, each of which has a wide range of applications and is 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 for cleaning and deoxidizing metal surfaces, as well as in processes such as electroplating, electrolysis and corrosion treatment. In addition, sulfuric acid can also act as a catalyst to facilitate certain chemical reactions.

Nitric acid: Nitric acid is mainly used for cleaning and corrosion of metal surfaces. It is a strong oxidizing agent that 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 can be 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 can be used in water treatment, textile dyeing and the pharmaceutical industry.

Please note that although these acids have a wide range of applications, they are all strong acids, which are highly corrosive and should be handled and used with appropriate safety measures. 》

The people of all dynasties were very happy when they saw the new comments.

Although they didn't understand some of what the comment on the canopy was saying, they still found their way to use it.

In particular, the canopy reminds them that it is also highly corrosive, so that they can take appropriate safety measures.

If it weren't for the prompts on the canopy, I'm afraid they would be brutal.

In particular, some people understand the effect of the hints on the canopy after making gunpowder.

At the same time, they were pleasantly surprised to see the effects of nitric acid.

So they got into action, experimenting and experimenting to find out how to make the fertilizer.

Qin Dynasty.

Qin Shi Huang was very happy when he saw the comments on the Tianmu, and he felt that he had learned some new knowledge in the Tianmu.

Ever since the canopy appeared in the sky, Da Qin had been learning new things on the canopy, and those Mo family disciples had also made a lot of things based on the information on the canopy.

For them Daqin, the more important ones are the four great inventions.

Whether it is papermaking or printing, it has made him a qualitative leap in Daqin.

And now the technology mentioned on the canopy is more on the basis of the original to make Daqin more icing on the cake.

But even so, Qin Shi Huang hopes that everyone can learn more and more.

Such a Great Qin will gradually become stronger, and the lives of those people will also get better and better.

What made him feel deeply was that after learning to make gunpowder on the canopy and applying gunpowder to the battlefield, those Huns did not dare to step into Daqin.

They thought that the gods were angry, and that they would be punished for their transgressions.

Not only that, but bombs made of gunpowder can also make the Xiongnu's horses panic, so that the Xiongnu no longer have mobility, which is also not an advantage for Daqin?
