Chapter 600

Li Tian has been holding this position for nearly an hour. His arm is a little stiff. Fortunately, there is no big problem. He can only move once in a while.

Tang Wan also woke up at this time. She was surprised when she saw that the blisters on Tang Xin's skin in the bath were really small.

Why on earth is all this?

"Can you cure her with salt water?"

Tang Wan asked in a low voice.

"Well, at least it can get her out of danger."

Li Tian used, is a very common chemical method, known as salting out method. This method should be in junior high school textbooks, of course, he did not learn, these are all with the ghost king, just met, at that time the ghost King explained the principle to him in detail.

Salting out method, strictly speaking, means that only a certain amount of salt can be melted in certain water, which is called salt saturation. If the water in the bathtub is salty, then after contacting the blisters on the skin, the water in the bathtub will slowly absorb the water in the bubbles, making the saturation of both sides consistent.

Because the water in the body is certainly not as salty as the water in the bathtub, the bathtub will absorb a lot of water from the skin, making the saturation (salinity) of both sides reach a balance. The skin acts like a filter, which can take hours to complete, but does not cause fatal damage to a person's skin.

If you go to the hospital, you may directly think that the blisters should be removed, and then the water inside will be discharged, but that piece of skin will be wasted and will slowly fall off.

According to Tang Xin's current situation, at that time, 80% of her skin will fall off. At that time, she can't accept the whole body, especially the one on her face.

In this way, at most, a few broken blisters will leave a little scar, which is because the skin of that piece is broken, and salt can enter. However, salt is slightly corrosive. Its chemical composition is sodium oxide, and sodium is a kind of metal.

Broken skin, will certainly be the degree of erosion, after recovery, may leave a light scar, but also through the maintenance of the day after tomorrow to recover.

Just like a glass cup, which is cut by a piece of filter paper in the middle, put salt water with high concentration on one side and fresh water on the other side. Then the water on both sides will be the same salty after a period of time. This is because the water and salt on both sides are exchanged through the filter paper, and when the salt concentration of both sides is the same, it will stop.

Skin and filter paper are not the same, water from the skin out of the inside is easy, just like sweating, cells a little movement will not be a problem.

But water from the skin to enter, it is more difficult, because pores on the outside of the water, there is a natural repulsion, otherwise you swim a few hours, is not the direct weight gain dozens of Jin?

It is to use the huge concentration difference of salt inside and outside the skin to let the water in the bathtub slowly absorb the water in tangxin's body without damaging her skin.

Can you understand

After Li Tian explained the principle of this kind of thing, Tang Wan understood it immediately, because she seemed to have learned it in junior high school. The saturation of salt seemed to be a number. I don't know whether it was thirty-six or thirty-seven. All these years have passed.

36、 It means that in 100 grams of water, 36 grams of salt can be dissolved. If it exceeds this weight, it will not dissolve. It will precipitate in it like crystal.

Although thought of, but after all, is the textbook inside the thing, who can apply to the real life? Tang Wan used to study very well, and never thought of it. Even if Li Tiandu had already taken out the salt.

This is the gap. Maybe Li Tian didn't learn anything, but what he learned can be used at any time.

After telling the story, Li Tian said, "that If you can keep your body going, can you make me something to eat? "

It's already 12 o'clock at noon. Li Tian is starving. This kind of thing is endurance.

Tang Wan immediately said, "OK, I'll do it now. There are some ready-made vegetables and meat in the kitchen."

Seeing Tang Wan turn around and walk outside, Li Tian suddenly calls out: "that There should be no salt in the kitchen. You should go out and buy some. Besides, the department store nearest to us is gone

There is no salt, you can't scoop a little water from the bathtub to stir fry. Thinking of that picture, Li Tian suddenly lost his appetite.

"Well, I'll go out and buy some."

After more than an hour's rest, Tang Wan felt that her energy was good. It should be no problem to go out and buy something.

Sitting in the car, Tang Wan suddenly felt that the world was so quiet that there was no worry at all. It seemed that as long as Li Tian was by her side, all the troubles would disappear automatically.

Passing Li Tian's gate, Tang Wan discovers that Wen Wen is playing with Wang MA in the yard. She wanted to shout, but Tang Wan can't help thinking about the situation at home.

Safety is good. I don't have to worry about Wen Wen.As for the two men Whatever they do or die for.

Tang Wan made up his mind that he would never let those two guys disturb his life any more. From their shamelessness to the betrayal of his sister, he was no longer his parents.

Do you owe them? Yes, he owes his life, but how much has Tang Wan done for them these years? Even if it is not clear, Tang Wan will not feel too guilty.

It's them who have dissipated a little bit of affection all the way up to now.

Because there was no salt in the nearby department store, Tang Wan ran a little farther. There were some dirty marks on her clothes, but she didn't care.

Meanwhile, she bought some vegetables and meat. Tang Wan decided to make a good meal to reward Li Tian.

When she got home and saw Li Tian still sitting there, Tang Wan was very comfortable. These days, she was really tired. Finally, all the pressure in her heart disappeared.

This man can always solve all difficulties and troubles.

If If there is no accident, are the two people already

On that day, Tang Wan was ready for everything, if not for the two people who made trouble all of a sudden.

He must hate himself now, right? But If there is no intersection in the future, then Do you want to give it to him once?

At least, he has left something in his life, he will not have regrets, even if he can not get
