Can acetic acid remove rust and what is generated

According to basic oxides.

The principle of being able to react with acids, with acetic acid.

Rust can also be removed, but the reaction is slower.

Ferric acetate (Fe(CH3COO)3) and water (H2O) are generated.

Chemical equation.

is 6CH3COOH+FE2O3=2FE(CH3COO)3 + 3H2O

Ionic equations.

is H+ +Fe2O3=Fe3+ +H2O, where: Basic oxide refers to an oxide that reacts with water to form only a base, or reacts with an acid to produce only salt and water (Note"only"word).

Metal oxides.

Generally basic oxides, but there are exceptions, such as manganese heptaoxide and chromium trioxide.

1.Wipe the stain with a 15% acetic acid solution (15% tartaric acid solution is also acceptable), or soak the stained part in the solution, and rinse it with water the next day.

2.Stain with a 10% citric acid solution.

then soak in concentrated salt water and rinse the next day.

3.If white cotton and cotton blended fabrics are stained with rust, take a small grain of oxalic acid (available in pharmacies) and put it on the stain, drip some warm water, rub it gently, and then rinse it with water. Pay attention to the operation to be fast and avoid corrosion.

4.It can be washed with 2 oxalic acid solution in about 50 warm water to remove, and then rinsed with water. After grinding 3-4 vitamin C tablets into powder, sprinkle on the stains of soaked clothes, and then scrub with water several times to remove rust stains.

If it is rust stains, you can use 10 oxalic acid and citric acid to add water mixture to soak the rust area, then soak it in concentrated salt water, and wash it after 1 day.

5.The easiest way: If you have fresh lemon, you can squeeze out its juice and drop it on the rust stain and rub it by hand, repeat several times until the rust stain is removed, and then wash it with soapy water.

1.Acetic acid can react with iron oxide, but the product is easily hydrolyzed into iron hydroxide precipitation, so it is not good to use acetic acid to wash rust stains on clothes.

2.Iron oxide can be washed off after reduction with hot oxalic acid solution, or it can be washed with phosphate mixed with acetic acid, and iron ions can be washed off by phosphate complexation.

Yes, iron acetate and water are generated.

Yes. Ferric acetate (trivalent) + H2O is generated

OK. First, the metal is immersed in white vinegar for several hours to allow the chemicals in the white vinegar to fully react with the rust layer. If the item is too large to be immersed in the white vinegar, pour a layer of white vinegar on top and allow it to condense.

It is also possible to soak a rag in vinegar and wipe the metal. Soak the brush in vinegar and scrub the rust with the brush. Rinse off the remaining vinegar with clean water to prevent vinegar marks.

Method: 1. First, soak the metal in white vinegar for several hours to make the chemicals in white vinegar fully react with the rust layer.

2. If the item is too large to be directly immersed in white vinegar, pour a layer of white vinegar on top and wait for it to condense. It is also possible to soak a rag in vinegar and wipe the metal.

3. Soak the brush in vinegar and scrub the rust with the brush.

4. Rinse the residual vinegar with water to prevent vinegar marks.

Vinegar can be used to remove rust.

White vinegar should be used. Because the general colored vinegar contains more pigments and other food additives than white vinegar, and these food additives are likely to produce a large number of ions in the solution, according to the electrochemical principle

The ion-rich solution can promote the oxygen absorption and corrosion of iron products and accelerate the oxidation (rust) of iron products

Of course, whether it is colored vinegar or white vinegar, after all, after removing rust, iron products will still be rinsed with water, so the "negative effect" of colored vinegar is still very insignificant, but it is better to use white vinegar in comparison, and the use of white vinegar does not have to worry about the trouble of dyeing items with pigments.

In chemistry, white vinegar is an acidic substance that can react chemically with iron, so it can be used to remove coupon. But one should be in moderation.

Yes, as long as it is calculated, it can remove rust, is there acetic acid in vinegar, it will metacompose with rust, it is rust that becomes salt that can be dissolved in water, so that the rust is removed, but after vinegar takes the rust out, it will continue to corrode iron, the surface of iron is no longer smooth, and iron is easy to rust. If you can only use vinegar to remove rust, it is best to use hot vinegar and not wash it for too long to prevent the iron from being corroded.

Rust removal is because rust is iron oxide, vinegar is acid and can react with iron oxide; Iron rusts because iron rusts require a moist environment as well as some air, and vinegar is able to provide such an environment. The process of iron rusting can be divided into two categories: 1. Chemical corrosion, where iron reacts directly with oxygen at high temperature to obtain iron oxide.

2. Electrochemical corrosion (common), which is divided into two types: hydrogen evolution corrosion, corrosion that occurs in a humid environment with strong acidity. 2. Oxygen corrosion is the most common in nature.

Conditions: Impure iron, air, humid environment. The truth is:

In a humid environment, impure iron (containing carbon) forms iron--- oxygen – water – countless tiny galvanic cells. Iron: Negative electrode:

fe-2e-=fe2+；Carbon: cathode: 2H2O+O2+4E-=4Oh-; fe2+^+2oh-=fe(oh)2；4fe(oh)2+2h2o+o2=4fe(oh)3；2Fe(OH)3 = water loss in the air = Fe2O3·NH2O [rust] + (3-N)H2O.

The commonly used methods to prevent iron rust are: (1) Forming an alloy to change the internal structure of iron For example, adding chromium, nickel and other metals to ordinary steel to make stainless steel greatly increases the rust resistance of steel products; (2) Covering the surface of iron products with a protective layer is a common and important way to prevent rust of iron products According to the different components of the protective layer, it can be divided into the following types: a Coating mineral oil, paint or firing enamel, spraying on the surface of iron products For example:

Carriages, buckets, etc. are often painted; The machine is often coated with mineral oil, etc.; b Plating a layer of metals that are not easy to rust by electroplating, hot plating and other methods on the surface of steel, such as zinc, tin, chromium, nickel, etc. c. Use chemical methods to generate a dense and stable oxide film on the surface of iron products to prevent rust of iron products; (3) Keeping the surface of iron products clean and dry is also a good way to prevent iron products from rusting.
