Datang: Time travel in two months, wait online, hurry up!

Soon, he put on a mask, gloves, and goggles according to the experimental rules, and then started his first chemical experiment!

PS: Please collect!Ask for flowers!Ask for a review ticket!

Chapter 35 Crazy again!All experiments were successful!

The chemicals needed to make soap are sodium hydroxide solution, alcohol, salt water, vegetable or animal oil, and water.

The equipment needed are alcohol lamps, pottery evaporating dishes, glass rods, beakers, and filters.

Alcohol, salt water, vegetable oil and water, he does not make them separately, these are all bought ready-made.

Because these things existed in ancient times, they can be used directly.

At most, the alcohol is not pure enough, but a simple distillation is enough.

So he just needs to make a sodium hydroxide solution.

Sodium carbonate is needed to make sodium hydroxide.

Among them, sodium carbonate is also known as 'soda ash', and sodium hydroxide 'fire soda' is known as the two most basic alkalis in the chemical industry!

At the same time, there are three acids, nitric acid, sulfuric acid, and hydrochloric acid, which are collectively referred to as 'three acids and two bases'!

These three acids and two bases can be described as the foundation of the chemical industry.

With these three acids and two bases, it is equivalent to establishing the most basic chemical industry, which is a milestone development.

So after Li Ke traveled to the past, if he wanted to develop the chemical industry, the first thing he did was to get out these three acids and two bases.

Because too many chemical products need these three acids and two bases!

But he didn't read the books for nothing for a month, and now the preparation methods of the three acids and two bases are all in his mind.

Now, he can prepare these two bases.

Next, he uses various raw materials, adds raw materials according to chemical equations one by one, conducts chemical reactions, and then produces the chemicals he wants.

Although it may be because it is the first time to do a chemical experiment, the movements of the hands are a bit rusty, but the overall general direction is correct, and there is no wrong operation.

After a series of operations, he prepared the sodium hydroxide solution he needed without any mistakes.

Next, the production of soap was officially started.

Pour part of the vegetable oil into the sodium hydroxide solution first.

At this time, there will be a problem, a large amount of oil floats on the solution, and it is not dissolved in the sodium hydroxide solution.

But this scene was as early as he expected.

At this time, he poured the prepared ethanol, which is alcohol, into the solution.

Because ethanol can increase the solubility of oil in lye.

Subsequently, the evaporating dish containing the solution was placed on the shelf, and the alcohol lamp below was lit to heat it up.

While heating, stir with a glass rod.

Soon, the fat dissolves into the solution.

Turn off the alcohol lamp, wait until the solution cools down, and add saturated saline to it.

The purpose of adding salt water is to allow higher fatty acid sodium salt and glycerin to fully separate.

After that, he continued to stir. After a while, he gradually saw a light yellow solid substance floating on the liquid surface.

"This is soap!"

Seeing the light yellow solid substance floating on it, Li Ke's eyes suddenly lit up, and a happy smile appeared on his face.

After all, this is the first time to do an experiment. Although the theory and procedures have long been familiar to me, I am still a little nervous.

Now that the experiment is successful, it must be very happy!

Stirring was continued, and the solution was poured onto the strainer after the light yellow solid material stopped increasing.

In this way, the filter net is full of this light yellow solid substance.

Then, these light yellow solid substances are poured into molds to form, and when these solid substances are solidified and formed, the soap is made.

"It looks simple, but it actually requires a solid chemical foundation and important chemical raw materials!"

Li Ke successfully completed the first experiment and successfully produced soap, which gave him full confidence!

But at the same time, he also felt the complexity of the subject of chemistry, all kinds of equations and the required raw materials, the same error will lead to different results.

"The first experimental project was successful!"

"Start the second!"

Li Ke opened the notebook, picked up a pen and ticked the back of the soap, indicating that this one had completed the experiment.

Next, he is going to experiment with toothpaste!

Likewise, list the chemicals that make toothpaste first, and then make those chemicals.

The main components of toothpaste are three chemical materials: sodium lauryl sulfate, sodium carbonate, and ammonium chloride.

As before, Li Ke first prepared these three chemical materials using the equipment in the laboratory and the raw materials purchased.

Then prepare sodium lauryl sulfate, pour warm water into it, and stir with a glass rod.

Then add the corresponding amount of sodium carbonate and continue stirring.

Then add a certain amount of ammonium chloride into it, and then keep stirring.

It's done when it's blended into a paste.

Of course, you can also add mint and the like to it.

After finishing this experiment, he also put a tick behind 'toothpaste'.

Next, I fell into a boring chemical experiment.

When doing the first chemical experiment, Li Ke was very excited. After seeing the success of the experiment, he was very happy.

But when he did the second, third, and fourth experiments, his whole body gradually became numb.

Even seeing that the experiment is successful, my heart is still silent, and there is no reaction.

But there is no way, no matter how boring it is, he has to endure loneliness and complete his experiments one by one in this laboratory honestly.

Of course, there are times when experiments fail.

At this time, he will go to the Internet to find the reason, or ask other people.

And that's why he endured the boring experiments here.

If he failed the experiment here, someone can ask, if he failed the experiment in the Tang Dynasty, it would be called "every day should not be done", and the earth would not work!

Soon, half a month passed.

In order to save time, he lived directly in the laboratory for half a month!

Anyway, there is a bathroom next to the laboratory, which has hot water for bathing.

So he took a few sets of clothes directly from home, and then lived here for half a month!

Order takeaway when you’re hungry, and rest when you’re sleepy!

He entered the state of madness again!

And it's worth it for him to be so crazy, because in the past half a month, all the experiments he planned before have been completed!

Among them, the experiment has a success rate of about 70%, and only 30% of the experiments fail.

However, he searched for the reason on the Internet, and after asking someone to inquire, he conducted the experiment again.

Until now, all his experiments have been successful!

PS: Please collect!Ask for flowers!Ask for a review ticket!

Chapter 36 The essence of human progress is boiling water!

For the past half month, he has been doing these boring experiments.

Sometimes it will fail inexplicably, and then start to find the reason boringly and try again.

The next experiment will not start until the experiment is successful and the most standard and correct operation is found.

To be honest, he was a little surprised how he persisted.

"Maybe everything is for the future, for controlling destiny!"

Li Ke shook his head involuntarily, and said with a light smile.

He knows very well that if he wants to get what others can't get, he has to do what others can't!

Every experiment he does now, every thing he makes is a card in his hand after time travel!

Only the more cards in his hand, the bigger the cards.

He can control his own destiny!

Therefore, he has been brainwashing himself, telling himself to experiment seriously, not to let go of any details.

In this way, he actually forcibly found happiness and motivation in the experiment!

Others brainwash you, that's painting cakes.

But if you brainwash yourself, you will be invincible!

But fortunately, the experiment in the state of madness for half a month, the harvest is also very huge!

Not only did he complete experiments in chemistry, he even completed some experiments in physics!

Such as steam engine, compass, gunpowder, power generation and other experiments.

Of course, the experiments he mentioned refer to laboratory projects, not real mass-produced ones.

For example, in the steam engine experiment, he will definitely not actually build a steam engine, which is obviously unrealistic.

Let's not talk about the need for a lot of steel, and finding a factory to process these.

As far as the area of ​​this laboratory is concerned, that's not enough!

The steam engine experiment he was referring to was a simple steam engine made by himself, using Coke cans, infusion tubes for transmitting steam, alcohol lamps and other equipment.

Simple is simple, but the principle is exactly the same as that of a real steam engine.

He even bought a real steam engine model from the Internet! (There are pictures)

Although it is called a model, it can actually be used.

Just a real steam engine scaled down!

He used an alcohol lamp to heat the cylinder of the steam engine, and the water inside was heated to produce hot steam.

Through the principle of thermal expansion and contraction, hot steam expands and then pushes the piston of the steam engine to perform work.

A thermal expansion and contraction is a movement of the piston.

Repeated thermal expansion and cold contraction has formed a steady stream of power!

As long as the boiling water continues, the steam will continue, and the power will continue!

How else can we say that the progress of human beings is how to study boiling water!

A steam engine boils water and converts heat energy into kinetic energy.

A thermal power plant also boils water, converts thermal energy into kinetic energy through a steam turbine, and then converts kinetic energy into electrical energy through a generator.

Even nuclear power plants use nuclear energy to heat water to boil water to generate electricity.

Even the current nuclear-powered aircraft carrier sounds quite advanced.

But that also has to boil water, and it uses a steam engine!

It's just that the steam engine used to burn coal to boil water, but now it uses nuclear energy to boil water.

After the steam engine, Li Ke experimented with gunpowder.
