Magnesium oxide reacts with ferric oxide, what is ferric oxide

Can't react, right, magnesium and iron here are already the most ** Note: magnesium oxide should not be enough to turn ferric tetroxide into ferric oxide Obviously, magnesium is more active than iron You have to pump oxygen out of magnesium and give it to iron, why do people ?..

So what are you going to oxidize?

PS: There is no such thing as iron oxidizing oxygen. It's always been oxygen to oxidize other things, and it's over, and magnesium peroxide is there. However, I still don't think it's possible that oxygen is oxidized.

It is possible to use magnesium powder, magnesium hot agent.

MGO does not react.

Magnesium peroxide is present, and alkaline earth metals even have ozonoxides.

Wrong. MGO2 does not react with Fe3O4.

As the most advanced metal compound, it cannot be used as a reducing agent to react, that is to say, the most advanced metal compound cannot reduce other metal oxides, because it can no longer be oxidized.

Also, ferric oxide is a very complex metal oxide, and it can be seen that its valency is 8 3 In fact, it is not ferric tetroxide in the true sense, it is a mixed oxide of iron, and a deeper reaction is not required in high school You can determine the redox aggregate reducing agent in the redox reaction according to the metal activity sequence table.

I hope your chemistry grades are getting better and better!

Magnesium oxide does not react with ferric tetroxide. Magnesium peroxide cannot be generated, as ferric tetroxide is not so oxidizing.

To reduce iron, suitable reducing agents should be selected, such as C, Co, H2, etc.

Ferric oxideis an oxide, an oxide that belongs to iron. The chemical formula of ferric tetroxide is Fe3O4 and the relative molecular weight is. It is commonly known as iron oxide black, magnetite, and black iron oxide.

It is a magnetic black crystal, so it is also called magnetic iron oxide.

Introduction to ferric tetroxide:

Ferric tetroxide, commonly known as iron oxide black, magnetite, and black iron oxide, is a magnetic black crystal, so it is also called magnetic iron oxide. Don't think of it"Ferrous metaferrate"[Fe(FeO2)2], nor can it be regarded as ferrous oxide.

FeO) and iron oxide (Fe2O3), but can be approximated as a compound composed of ferrous oxide and iron oxide (FeO·Fe2O3

This substance is soluble in acid solution, insoluble in water, alkali solution and ethanol.

Organic solvents such as ether. Natural ferric oxide is insoluble in acid solution and easily oxidized to iron oxide (FeO) in the air in a humid state. It is commonly used as a pigment and polishing agent, and can also be used in the manufacture of audio tapes and telecommunication equipment.

Ferric oxide has anti-corrosion effects, such as the bluing of steel parts (also known as burnt blue and baked blue) is the use of alkaline oxidation solution oxidation to form a layer of blue-black or dark blue Fe3O4 film on the surface of steel parts, which is used to increase corrosion resistance, gloss and beauty.

Ferric oxide and hydrochloric acid reaction: Fe O +8H = 2Fe + Fe + 4HO

The formation of ferric tetroxide is a very basic oxidation reaction, the metallic iron is violently burned in oxygen to produce black ferric tetroxide, which is the most common magnetite in life.

The answer is correct, but I don't think the way of thinking is quite right!

Because the valency of Fe3O4 is not the same as that of Fe2O3 and FeO.

Ferric oxide is a ferrite, i.e., Fe2+Fe3+(Fe3+O4) (i.e., FeFe(FeO4) preceding 2+ and 3+ represent the valence state of iron). In Fe3O4, iron shows two valence states, one iron atom shows +2 valence, and two iron atoms show +3 valence, so ferric oxide can be regarded as a compound composed of FeO and Fe2O3.

fe3o4+8hcl==fecl2+2fecl3+4h2o

Fe3O4 is not a mixture or combination of FeO and Fe2O3, but a ferrite Fe[FeO2)2], and the cation is a +2-valent ferrous ion. The ΔFGM of this substance in the standard state is -1015kjmol; From the data, it can be seen that the δRGM of Fe3O4+8H+=Fe2++2Fe3++4H2O is a number less than 0, so the reaction is still thermodynamically feasible (H+ concentration is 1mol L); But natural Fe3O4 is insoluble in acids, which is the reason why the reaction rate is too slow. The powder form can be dissolved in a sufficient concentration of acid.

The final product is FeCl2 and FeCl3, so it should be fine for you to think of Fe3O4 as a Fe2O3 and a FeO, but I don't know if this is the case in other topics.

Well, yes, but according to your method, you should get fe3o4+8hcl=4h2o+fecl2+2fecl3.

And the phenomenon is: the solid dissolves, producing a yellow-green solution.

Parenchymal Fe3O4 is a ferrite of ferrous ferrite Fe(FeO2)2

Ferric oxide (Fe3O4) and iron (Fe) can be reversed. In fact, ferric oxide can be reduced to iron.

When ferric tetroxide reacts with iron, the products of iron and carbon dioxide can be obtained

The high megawatt reaction of Fe3O4 + 4Fe ->7Fe + 2CO2 is a reduction reaction in which ferric tetroxide is reduced to iron and at the same time oxygen is transferred to carbon dioxide.

It is important to note that this reaction requires appropriate conditions, such as high temperatures and appropriate reaction strip modules. In addition, the rate of the actual reaction and the amount of product also depend on the molar ratio of the reactants and the reaction conditions. Hope it helps.

First of all, to test iron, it is necessary to use the reducibility of iron.

That is to say, the iron should be oxidized, so add copper oxide to calcinate to see if the copper oxide is discolored. If there is iron, then the iron will reduce the copper oxide to copper, which means that the finger will disappear as if it were copper with a red color.

Second, ferric tetroxide, to use the oxidation of ferric iron in ferric tetroxide. First add dilute sulfuric acid to turn all the solids into a solution, and then add copper sheets (or copper wires) to see if the copper sheets are reduced and whether the solution is blue? If the copper flakes are reduced, then the trivalent iron has oxidized the copper to divalent copper ions.

This is because copper ions cannot be oxidized if there is only iron. ）

I hope to help the landlord.
