What happens when you run into a sore hand? What happens when your hand touches aluminum sulfate

Sulfuric acid is highly corrosive, and contact with ** can lead to **, muscle, bone damage, such as a large area of scalding should be treated in time. If your hands are exposed to sulfuric acid, you should rinse them with plenty of water in time and go to the hospital to assess the degree of burns. Debridement can be performed if necessary.

A few years ago, I accidentally touched a colleague's hand, and my first reaction was to quickly pull it back. She laughed at her.

Let me think.

Actually, your hands were got with sulfuric acid.

Don't rinse with water at all.

Because water will speed up the corrosiveness of sulfuric acid.

In addition, the sulfuric acid that you get a little bit by hand will turn into a large lump due to water, so the best thing to do is to do it.

Wipe with a rag first.

Wait before rinsing with water.

That's for the best. But now that you've been a day.

Then it is recommended that you go to the hospital to have a look.

After all, this is sulfuric acid and nothing else.

It's very corrosive, and it's better to check it out for safety, hehe

Take my answer

After touching sulfuric acid, rinse with a large amount of water, although sulfuric acid will release a lot of heat when it touches water, but rinsing sulfuric acid with water will not be higher than 40 degrees, so it will not burn **, and wiping it with a rag will expand the corrosion area. Therefore, you should rinse with plenty of water before wiping the area you just touched. Then rub baking soda for a few days in a row, or some weakly alkaline, caustic soda can not be because the alkalinity is too strong.

When I was in school, I did the experiment, I also came across, the teacher taught us to dry with a cotton cloth first, and then rinse with water, to rinse for a long time, 5 minutes is the best!!

QThe use cotton to blot it dry without water

You must not dare to use water, you must use nitrate pickling to neutralize the effect.

Wash with water and don't use anything else.

If your fingers touch a strong acid (strong alkali), you should immediately rinse it with plenty of water, then apply a sodium carbonate solution (boric acid, if you don't have it, you can also use vinegar instead), and then go to the hospital for further treatment.

Do not wipe with a rag or napkin (wipe a piece of skin), immediately rinse with plenty of cold water, and apply 3 to 5% NaHCO3 solution with acid, and apply boric acid solution with alkali.

Rinse directly with a lot of water, and in some places write what acid or alkali to use to neutralize, these are just things that are said in books, not practical, and there is no need to do this.

That's what the book says, but the other day I was splashed with 1:1 hydrochloric acid, and it was fine, and some people said that the acid had gone bad, and then I measured it, and I diluted it ten times, and I measured the pH level, and I realized that the textbook was bluffing.

You haven't done anything until now, you won't be doing well, these things haven't heard of it at a later stage, and your hands didn't have any problems at that time, just wash them off.

Concentrated sulfuric acid will heat up when it encounters water, so a large amount of water will be evaporated at once, so you should take your time when diluting it. Sulfuric acid should be wiped clean and cleaned within 1 minute when it touches the hand, soap and other alkaline neutralization, first touch the hand do not panic, pure sulfuric acid can only cause the epidermis to burn within half a minute, immediately wipe off the excess with a cloth, and rinse the remaining faucet at the same time to quickly clean up the acidity in the fingerprint.

Concentrated sulfuric acid. Also known as oleum. When the concentration is too high, smoke will emit when the reagent bottle is opened. The high concentration of water dissolves and exothermic, and the water turns into water vapor. . .

After touching your hands, wipe them dry with a dry cloth and wash them with 5% NAC03 solution.

The reasons are the same as 407138051.

Our chemistry teacher said that we should first rinse with a large amount of water [sulfuric acid will be exothermic when exposed to water. so。。Then dry it with a cloth and then apply NaHCO3 in a slightly different order from the book.

The acid should be wiped off immediately with a towel. How can sulfuric acid smoke when it meets water?

It's not too much of a problem, if you want to corrode, it will corrode instantly.

It's nothing, just wash it with water.

It's generally dilute sulfuric acid, and it's fine.

It must be rinsed with plenty of water and then with an alkaline solution.

Don't you have soda or soda in your house? Wash it and neutralize the acid and alkali.

There are no consequences if you rinse it off immediately with water.

If there is no burning sensation at the moment, it will be fine, just rinse it with water.

It hurts, and you can't use water when you have concentrated sulfuric acid.

It's fine to flush with water, and it will burn out if you don't treat it**.

Wipe off the sulfuric acid from the surface with a damp rag, then rinse with water and apply sodium bicarbonate.

Because concentrated sulfuric acid has strong oxidizing properties, and during the dilution process, a large amount of heat will be released, which will burn out**. Choose to wipe it off with a rag and apply a sodium bicarbonate solution.

First wipe off the sulfuric acid, then rinse with ice water, remember not to wash with water at the beginning, it will dilute the sulfuric acid, and it will be more serious.

Wipe clean with a dry cloth, rinse with water, and rinse with 5% sodium bicarbonate.
