What substances can corrode metal not just iron .

Both acids and alkalis can be used and some acidic and alkaline gases can be used.

I don't know if it's because of chemistry!

It must be an electrolyte that can react with metals, and of course strong metal acids can corrode.

Like aluminum, strong alkali can also corrode.

Some metals can also be passivated with an appropriately strong acid.

If there is an electrolyte, it can corrode the metal, and the metal will carry out the galvanic cell reaction on its own, and the electrons will be transferred to oxygen, and it will be oxidized by itself, that is, it will be corroded.

Whether it is stainless steel or stainless iron, it contains Fe(3+) in it, and eggs contain protein in it, and he can produce ammonia (NH3), so we sometimes smell hard-boiled eggs and have a faint smell. From this, it can be seen that the reaction Fe(3+) 6NH3 = Fe((NH3) 6)(3) (hexaamimonia iron ion). I don't know if you're happy with this.

Acids can, like sulfate and nitric acid, can corrode most metals.

Corrosion is an oxidation reaction.

Therefore, as long as it can react with iron (metal), it can corrode it.

The essence of metal corrosion is that the metal elements are oxidized.

Metal corrosion: metal corrosion can be divided into two kinds, chemical corrosion and electrochemical corrosion, chemical corrosion is the corrosion phenomenon produced by the direct redox reaction between the metal or alloy and the contact, it should be noted here that it must be a pure metal or alloy, and then electrochemical corrosion is the corrosion phenomenon caused by the galvanic cell reaction caused by the contact between the impure metal or alloy and the electrolyte solution, and the galvanic cell reaction occurs, there will definitely be a microcurrent, and the same should be paid attention to the material, it is an impure metal or alloy.

For example, iron rust is what kind of corrosion occurs.

Both kinds of corrosion will occur at the same time, first of all, our common iron is impure iron, which contains a small amount of carbon, so the pure iron in it will be chemically corroded by itself, and then iron can also form a galvanic battery with carbon, iron as the positive electrode, carbon as the negative electrode, chemical corrosion, electrochemical corrosion is the most common.

Electrode reaction: hydrogen evolution corrodes the negative electrode reaction, and the iron loses two electrons and becomes ferrous ions; The cathode reacts, and two hydrogen ions get two electrons to become hydrogen.

Oxygen absorption corrodes the negative electrode reaction, and the iron loses two electrons and becomes ferrous ions; The positive electrode reacts, and oxygen gets four electrons to become hydroxide ions.

The most essential difference: the positive reaction is different, and after the positive reaction is different, the natural total reaction will be different.

Summary. For example, vinegar and salt can corrode the metals such as steel and aluminum alloy, which are common in life; Humid air does not need to be sold, it can slowly corrode the common metals of steel and aluminum alloys in life.

If you want to corrode the metals commonly found in life, such as steel and aluminum alloys, you can use toilet cleaner (its main ingredient is acid, which is easy to buy on the market), and you can also go to the chemical market to buy hydrochloric acid and sulfuric acid.

For example, vinegar and salt can corrode the metals such as steel and aluminum alloy, which are common in life; Humid air does not need to be sold, it can slowly corrode the common metals such as steel round and aluminum alloy in life. If you want to corrode the common metals such as steel and aluminum alloy in your life quickly, you can use the toilet cleaner orange Paixiang (its main ingredient is acid, which is easy to buy on the market), and you can also go to the chemical market to buy hydrochloric acid and sulfuric acid.

Rapid corrosion of iron.

What melts iron fast?

Concentrated sulfuric acid. Iron is most afraid of concentrated sulfuric acid, and concentrated hydrochloric acid melts quickly. They can react with iron-lead fronts to quickly dissolve iron. Sustained high temperatures, at least more than 1500, can also quickly melt iron into liquid.

Iron and steel corrosion is mainly electrochemical corrosion, of which oxygen absorption corrosion is the main corrosion.

There are two types of iron and steel corrosion: chemical corrosion and electrochemical corrosion, and the conditions for chemical corrosion are generally rarely available, so electrochemical corrosion is the main thing in nature, hydrogen evolution corrosion occurs under acidic conditions, and oxygen absorption corrosion occurs under neutral or alkaline conditions.

Summary. Hello, it's a pleasure to serve you.

Acid and alkali can corrode iron, but the speed of corrosion depends on the concentration of acid and alkali, and strong acids and alkalis with high concentrations corrode relatively quickly. Strong acids are common concentrated sulfuric acid, concentrated nitric acid, and strong alkalis are common sodium hydroxide.

What substance corrodes steel the fastest.

Hello, it's a pleasure to serve you.

Acid and alkali can corrode iron, but the speed of corrosion depends on the concentration of acid and alkali, and strong acids and alkalis with high concentrations corrode relatively quickly. Strong acids are common concentrated sulfuric acid, concentrated nitric acid, and strong alkalis are common sodium hydroxide.

How long does it take to rot.

How can the motor rot.

Hello, this if the concentration is high may be within half an hour. Yes. Hello.

There are usually four types of corrosive fluids used to corrode metals, namely acidic, alkaline, oxidized, and coordination;

Acidic, mostly using hydrochloric acid, and in a few cases, sulfuric acid, which can corrode most common metals such as iron, lead, aluminum, and manganese;

Alkaline, mostly sodium hydroxide or potassium hydroxide, can corrode aluminum, silicon (silicon industry and metallurgy are inseparable) and other amphoteric metal materials;

Oxidation type, which is the most varied, because most metals will be passivated or inert, so nitric acid, aqua regia and other substances are used for corrosion, and the oxidation is stronger under acidic conditions, which can be used to corrode titanium, chromium, gold, silver, copper, platinum and other materials that are not easy to be chemically processed;

There is also a kind of corrosive fluid that is coordinated, in fact, in order to reduce the electrode potential of the metal, it is used in conjunction with oxidants, such as CN-, EDTA, fluorine, etc., and can be used for copper, gold, bismuth, tin and other metals that are easy to coordinate.

Of course, if you don't talk much about potassium and sodium, water will corrode.

Answer: Iron oxide is not an iron compound.

Explanation: Iron compounds include various iron oxides such as FeO, Fe2O3, Fe3O4, etc. But iron oxide does not belong to iron compounds, because iron oxide is a mixed oxide, its chemical formula is FeO(OH)·NH2O, in addition to iron, there are also oxygen, hydrogen and other elements.

Expansion: Iron oxide has a wide range of uses in life, such as as pigments, catalysts, magnetic materials, etc. At the same time, iron oxide is also an important environmental pollutant, and high concentrations of iron oxide will cause harm to the environment and human health.

Iron compounds mainly include:

Iron metal Fe

Iron dioxide FEO

Ferric oxide Fe2O3

Ferrous chloride FeCl2

Ferrous sulfide Fes

Ferrous carbonate FeCO3

The main ones that do not belong to the iron group are:

Oxygen O2 Water H2O Carbon C

Nitrogen N2 calcium ca

Copper Cu Zinc Zn

Magnesium, mg, sodium, na, etc.

Although these elements or compounds are related to iron, they do not contain iron themselves, so they are not iron compounds. Iron compounds are all iron-centric compounds, and at least in the chemical formula, wide stool Fe is present.

In addition to some of the compounds mentioned above, other salt compounds such as sulfates, nitrates, and silicates do not belong to the Teshenyuan brigade compounds. As long as the crack does not contain iron, it is not an iron compound.

Therefore, in addition to Fe, FeO, Fe2O3, FeCl2, FeS, FeCo3 and other iron-containing compounds, O2, H2O, C, N2, Ca, Cu, Zn, Mg, Na, etc. are not iron compounds.

Iron compounds are compounds composed of iron and other non-metallic elements or other metallic elements. So what doesn't belong to the iron compounds? Obviously, copper (Cu), zinc (Zn), cadmium (Cd), silver (Ag), gold (Au) and other elements are not compounds composed of iron and other non-metallic elements, so they are not classified as iron compounds.

At the same time, iron oxides and ordinary oxides are not iron compounds.
