Chapter 600: Salting out

Li Tian has been maintaining this position for almost an hour, his arms are a bit stiff, but fortunately, there is no major problem, just occasionally move around.
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 much smaller.
Why is it all?
"Can she be cured with salt water?"
Tang Wan asked in a low voice.
"Forget it, at least it can get her out of danger."
What Li Tian uses is a very common chemical method called the salting-out method. This method should be in the junior high school textbook. Of course, he hadn't learned it. These were just encountered while following the ghost king. At that time, the ghost king explained the principle to him in detail.
The salting-out method, strictly speaking, means that only a certain amount of salt can be melted in a certain amount of water, which is called salt saturation. If the water in the bathtub has a relatively high salt content, then after contact with the blisters on the skin, the water in the bathtub will slowly absorb the water in the blisters, making the saturation of the two sides consistent.
Because the water in the body is definitely not as salty as the water in the bathtub, the bathtub here will absorb a lot of water from the skin, making the saturation (salinity) on both sides reach a balance. The skin is like a filtering device. This process may take several hours to complete, but it will not cause fatal damage to a person's skin.
If you go to the hospital, you might think that you just pick up the blisters and let the water out, but that piece of skin will be scrapped and will gradually fall off.
According to Tang Xin's current situation, 80% of the skin will fall off all over her body by then, and she will not be able to accept her whole body by then, especially the part on her face.
With this method, at most a few broken blisters will leave a little scar. That is because the skin is broken and the salt can enter. The salt is slightly corrosive and the chemical composition is sodium oxide. Sodium is a metal.
The broken skin will definitely be eroded to a constant degree. After it recovers, it may leave a faint scar, but it can also slowly recover through acquired maintenance.
Just like in a glass cup with a piece of filter paper cut open in the middle, one side contains very high concentration of salt water, and the other side contains fresh water. Then the water on both sides will be the same salty after a period of time. This is because the water and The salt content is exchanged through the filter paper, and it stops when the salt concentration of both sides is the same.
The skin is not the same as filter paper. Moisture comes out easily from the skin, just like sweating. There is no problem if the cells move a little bit.
However, it is more difficult for moisture to get in from the skin, because the pores have a natural repelling force against external moisture. Otherwise, if you swim for a few hours, wouldn't it be a direct weight gain?
It is to use the huge concentration difference between the inside and outside of the skin to allow the water in the bathtub to slowly absorb the water in Tang Xin's body without damaging her skin.
(Should you understand?)
When Li Tian explained the principle of this kind of thing, Tang Wan understood it immediately, because she seemed to have really learned it when she was in junior high school. The saturation of salt seems to be a number, not knowing whether it is thirty-six or thirty-seven. So many years have passed.
Thirty-six means that 36 grams of table salt can be dissolved in one hundred grams of water. If it exceeds this weight, it will not dissolve and will settle in it like crystals.
Although I thought of it, it is something in the textbook after all. Who can apply it to real life? Tang Wan studied very well before, and she never thought of this, even Li Tian had already taken out the salt.
This is the gap. Maybe Li Tian hasn't learned anything, but what he has learned can be used at any time.
After finishing the story, Li Tian said: "Um...If you can persist in your body, can you make me some food?"
It was twelve o'clock at noon, and Li Tian was too hungry. This kind of thing was enduring work.
When Tang Wan heard it, she immediately said, "Okay, I will do it now. There are some ready-made vegetables and meat in the kitchen."
Seeing Tang Wan turning around and walking outside, Li Tian suddenly called out to her: "That...there should be no salt in the kitchen. You have to go out and buy some. Also, the nearest department store is gone."
There is no salt, so I can't scoop a little water from the bathtub to stir-fry. Thinking of that scene, Li Tian felt that his appetite suddenly disappeared.
"Well, I'll go out and buy some."
After resting for more than an hour, Tang Wan felt that her energy was pretty good, and it shouldn't be a problem to go out and buy something.
After getting in the car, Tang Wan suddenly felt that the world was so quiet and there were no worries at all. It seemed that as long as Li Tian was by her side, all worries would disappear automatically.
When passing by the door of Li Tian, ​​Tang Wan found that Wenwen was actually playing with Ma Wang in the yard. She wanted to shout, but when she thought of the situation at home, Tang Wan still held back.
It’s good to be safe, so I don’t have to worry about Wenwen.
As for those two people...whatever they do.
Tang Wan made up her mind that she would never let those two guys disturb her life again. From the time they were shameless to betraying their sister, they were no longer his parents.
Do you owe them? Yes, I owe a life, but how much has Tang Wan done for them over the years? Even if it was unclear, Tang Wan would not feel too guilty.
It was them who wiped out a little bit of affection until now.
Because there is no more salt in the nearby department store, Tang Wan ran a little farther, and there were some messy marks on her clothes, but she didn't care anymore.
By the way, he bought some vegetables and meat, and Tang Wan decided to cook a good meal to treat Li Tian.
When she returned home and saw Li Tian still sitting there, Tang Wan felt very comfortable in her heart. These days, she was really exhausted. Finally, all the pressure in her heart disappeared.
This man can always resolve all difficulties and troubles.
If... If there is no accident, are the two people already...
That day, Tang Wan had already made all preparations, if it wasn't for the two people to make trouble suddenly.
He must hate himself now, right? But... if there is no intersection in the future, then... do you want to give it to him again?
At least, he has left something in his life, he will have no regrets, even if he can't get...
