After winning the prize, the whole network begged me to live broadcast the pastoral pension

Chapter 52 She became popular in variety shows 2
Aunt Yang's eyes darkened: "Potassium permanganate, what is this? Sweet, I don't understand what you're talking about, aunt."

Gan Tian thought for a while, and changed to a more intelligible way of saying: "It's the kind prescribed by the doctor when hemorrhoids are treated with sitz bath? Think about it carefully, has anyone gone to the hospital to prescribe this kind, and the doctor asked to take a pot Water, if you put some in it, it will turn into a purple liquid? It can reduce inflammation and relieve itching, take a sitz bath for a few minutes, and the itching will disappear."

The villagers at the scene shook their heads one after another, not wanting others to know their privacy:

"I've never had hemorrhoids!"

"Me neither, I don't know, I don't know!"

But some uncles and aunts at the scene tried hard to recall in their hearts that the medicine prescribed by the doctor for treating hemorrhoids was indeed purple-red water when poured into the clear water, which was similar to the phenomenon that the young man fell down just now.

Gan Tian sees it through, but there are many people who have never had hemorrhoids. Gan Tian changed his explanation: "It is the solution we use to treat watermelon and wax gourd wilt. Soak rice seeds and cabbage seeds in potassium permanganate for 10 minutes. In minutes, it can be disinfected and sterilized after rinsing, haven’t uncles and aunts used it?”

Aunt Yang suddenly realized: "So it is that one. I have a bottle at home, which is used to sterilize the seeds. It can also cure rice blast, tomato virus disease, watermelon wilt, Chinese cabbage soft rot. It is non-toxic and tasteless. Very useful."

Some other villagers also echoed: "My family also has rice seeds soaked with that thing, which can increase the germination rate. It is said that it can kill the germs attached to the surface of the seeds. The key is cheap!"

When it comes to crops, the villagers have practical experience.

"So, it's really not dirty water with a lot of bacteria?"

"Then it doesn't kill all the bacteria?"

"But the water is indeed clear, so what's going on?"

The villagers chattered again, waiting eagerly for Gantian to tell them the truth.

Gan Tian said: "It's actually very simple. Potassium permanganate and vitamin C, or potassium permanganate and oxalic acid and other reducing agents undergo oxidation-reduction reactions, and the color will fade into clear water. There should be reducing agents hidden on him. It's just poured in, and it's just playing tricks."

The young man who sold the goods was exposed by Gantian, and he was so angry that he rolled up his sleeves and rushed over to beat Gantian.

"Your mouth is full of ornithosis, see if I don't smash your mouth! ... Ah ... it hurts! Let go!"

He raised his hand ferociously, wanting to teach Gan Tian a lesson, but he didn't want Gan Tian to grab his wrist, turn his arm back, and kick his knee violently at the hollow of his knee, instantly crushing him to one knee on the ground.

The young man wanted to resist but couldn't break free from Gan Tian. He was so angry that he cursed in anger, "Bitch, let go!"

Gan Tian acted as if she didn't hear him, subdued him with one hand, fumbled in his pocket with the other hand, and finally found two vitamin C injections in his trouser pocket.

Gan Tian looked down: "It really is vitamin C!"

Gan Tian kicked the liar away, holding two small vitamin C injections: "Did you see it? He has vitamin C injections hidden in his pocket, and the secret of turning potassium permanganate purple-red water into clear water is This little vitamin C injection is not functional underwear. If you don’t believe me, whoever gets home and gets a bottle of potassium permanganate, I’ll verify it on the spot for everyone to see.”

A villager looked closely at the small potion, which really said vitamin C injection.

"Is it really vitamin C?"

"Why does vitamin C make potassium permanganate water clear?"

"I, I, I, I'll go home and get it, and I'll be right back!"

The villagers whose home was nearby rushed home.

The young man who was kicked to the ground by Gan Tian and couldn't even get up wanted to run away, but was quickly subdued by the villagers.

Another young man who wanted to drive away was also stopped by the villagers.

When the villagers got back a bottle of potassium permanganate, Director Jiang and the photographer also arrived. Director Jiang gave the photographer a look: Take a picture for me!
At this time, Gan Tian sent someone to fetch a basin of clear water from the well at the entrance of the village. She poured the potassium permanganate that the village name had brought from home into the basin, stirred it with a wooden stick, and soon the clear water turned purple. liquid.

The names of the villages surrounding her suddenly became clear.

"Old Gan's little granddaughter is right. It's really potassium permanganate, not dirty water full of bacteria. We were almost cheated!"

"No, I'm ready to pay for a pair of underwear."

Gan Tian broke apart a vitamin C injection, poured the injection into water, continued to stir, and said to the surrounding villagers, "Look at this, everyone, will the purple-red liquid turn into clear water?"

After a while, there was an exclamation from the scene.

"Changed! Changed! Really changed!"

"What's going on here? It's amazing?"

"It turns out that the secret is really not in the underwear, but in the vitamin C injection. It's sweet. Tell us, why?"

What must be said, lest more people be deceived.

Gan Tian said: "The principle is very simple, that is, the chemical knowledge that middle school students understand. Vitamin C and potassium permanganate have undergone redox. Vitamin C contains carboxyl groups and has reducing properties. The manganese in potassium permanganate is +7 Valence, with strong oxidizing properties, redox reaction occurs between the two, manganese ions change from +7 to +4, and the solution changes from purple to colorless."

Many villagers present seemed to understand and nodded.

Gan Tian said: "It doesn't matter if you don't understand, everyone just needs to know that mixing potassium permanganate and vitamin C can fade the color.

By analogy, if you apply it in your life, if you accidentally stain your hands and clothes when using potassium permanganate, soak it in vitamin C water, and the color will fade quickly.

If you accidentally eat potassium permanganate, you can also take a large dose of vitamin C gastric lavage to relieve potassium permanganate poisoning.

Even if the white shirt at home turns beige after wearing it for a long time, you can throw the clothes into the potassium permanganate water and soak for two hours, then wring the clothes dry, and continue soaking in the vitamin C water, and it will soon disappear. It can be restored to white, a proper whitening artifact. "

When the villagers heard the words, they all said that their knowledge has increased!

Netizens in the live broadcast room also praised it one after another.

[Vitamin C and potassium permanganate, so simple?Please accept the scumbag's knee, Get is here, it's amazing! 】

[My son did this little experiment in the kindergarten. These two liars are too abominable. They deceive the old people in the country with things that children know! 】
