However, because acetic acid is very acidic (ionization = and iron is not very active (but still more active than hydrogen), the rate of this reaction is very slow. The reaction of acetic acid with a large block of iron with a smooth surface is almost invisible, and the reaction of acetic acid with iron with a powdered surface with a rough surface can see bubbles. If iron is added to glacial acetic acid (anhydrous CH3COOH), no reaction occurs because the acetic acid molecule in glacial acetic acid does not ionize.

2hcl+fe=fecl2+h2↑
If you don't heat it, you can reflect it with iron powder!
Because any acid can react with the metal before hydrogen.
And acetic acid has HCL (hydrochloric acid) in it, so it's okay!

Anonymous users2024-02-09OK. I don't know if you've ever heard that cooking in an iron pot is good for iron supplementation. The human body does not absorb iron atoms and +3 valence iron ions. It can only be absorbed by humans when converted to +2 valence ferrous ions. So how did it come about? Vinegar, of course!

Anonymous users2024-02-08Acetic acid is too weakly acidic.
It will not be reduced by iron.
Otherwise, wouldn't you be able to put vinegar when cooking in an iron pot?

Anonymous users2024-02-07Yes, but it may be slower. Also, vinegar and acetic acid are two different things.

Anonymous users2024-02-04Acetic acid first reacts with iron to produce divalent iron and hydrogen, because it is too dilute, so the color of divalent iron can not be seen, and then the acetic acid pump is gone, and the divalent iron is oxidized by oxygen, plus water, to form Fe(OH)3, this is a reddish-brown precipitate, also because it is less, so it is lighter than soaking in water.
Because it is too thin, it is all dissolved, or there is very little that is not dissolved, but it is not visible, and the chemical formula is:
4fe2+ +o2+2h2o+8oh=4fe(oh)3<>

Anonymous users2024-02-03Summary. Hello, glad for your question. Iron and acetic acid react with ferrous iron because acetic acid is a weak acid that converts the oxide form of iron into ferrous iron, which is a more stable oxide form.
When acetic acid reacts with iron, the hydrogen ions in acetic acid convert the oxide form of iron into ferrous iron, which is a more stable oxide form. The oxide form of ferrous iron is more stable than the oxide form of iron, so it is more prone to reactions.
You've done a great job! Can you elaborate on that?
You're glad you asked. Iron and acetic acid react with ferrous iron because acetic acid is a weak acid that converts the oxide form of iron into ferrous iron, which is a more stable oxide form. When acetic acid reacts with cryptoferric, the hydrogen ions in the acetic acid convert the oxide form of iron to ferrous iron, which is a more stable oxide form.
The oxide form of ferrous sizzone is more stable than the oxide form of iron, so it reacts more easily.

Anonymous users2024-02-02Iron reeds react with acetic acid, what effect does the concentration of acetic acid have on iron.
Iron and hail acetate react, the reaction occurs on the surface of iron, and the reaction speed increases;
Considering that acetic acid is a weak acid, the ionization decreases with the increase of concentration, and the solution first increases and then decreases, if the measured acetic acid concentration just falls to the C interval that decreases with the increase of acetic acid concentration C, then the larger the C, the slower the reaction. However, the concentration of this C interval is very large, and it should be accompanied by Zheng not so high concentration.
No, if all the carriages are silent, it will be quite inconvenient, for example, the baby suddenly cries, and then for example, the business person suddenly has to have a meeting, etc., because when taking the high-speed train, it is impossible to say that everyone turns off their mobile phones, this kind of request is also unreasonable, as long as it is not intentional to make a lot of noise, some sounds I think are acceptable. But some people don't want to be affected, even a little sound can't do it, so the introduction of a silent car is very reasonable for this part of the people who have related needs, so I don't really understand what those who oppose think about it. <> >>>More
If you buy a product of 498 yuan or more at the retail price, submit a copy of your ID card.
