Equation for the reaction of ferrous hydroxide with nitric acid

There are two main production methods for solid polyferric sulfate: direct oxidation (one-step method) and spray drying. The production process of the direct oxidation method is to add ferrous sulfate to the oxidation furnace and dehydrate and oxidize it into basic iron sulfate at high temperature; Then it is mixed with sulfuric acid, cured and crushed to obtain solid polyferric sulfate.

The process is simple and the consumption of raw materials is small, but it is difficult to completely oxidize granular ferrous sulfate, the oxidation rate of Fe2+ is low, and there are many insoluble substances in the product, so it is not easy to meet the requirements of the national standard. The spray drying method is to dehydrate and dry the qualified liquid products with a high-speed centrifugal spray dryer (or pressure spray dryer), and the products fully meet the requirements of GB14591-93 indicators. The difference between the spray drying method and the direct oxidation method is that the former produces products with high iron content and can reach 23 More professional answers can be contacted....

To take place a redox reaction.

Because the iron in ferrous hydroxide is +2 valence, it has strong reducing property and is easily oxidized to +3 valence. And dilute nitric acid is a strong oxidizing agent:

Chemical equation.

3Fe(OH)2+10HNO3 (dilute) = 3Fe(NO3)3+NO+5H2O

The chemical equation for the reaction of ferrous hydroxide and hydrochloric acid.

For: ferrous hydroxide and hydrochloric acid react to form ferrous chloride and water. The reaction phenomenon is that the white precipitate of the branch gradually dissolves to form a light green solution. Example: The ionic equation for the reaction of ferrous hydroxide and hydrochloric acid.

is: Fe(OH)2+2HCl=FeCl2+2H2O.

Resolution: Ferrous hydroxide reacts with hydrochloric acid to form ferrous chloride and water. Therefore, the ion equation is: ferrous hydroxide and hydrogen ions react to form iron ions and water.

Ferrous hydroxide, with the chemical formula Fe(OH)2, is a white solid. Insoluble in alkaline solution, insoluble in water, soluble in ammonium chloride.

When heated, it will decompose into iron oxide and water. Pole in the air.

It is easily oxidized to iron hydroxide and becomes a reddish-brown color. When ferrous hydroxide powder is sprayed in the air, it immediately burns and emits sparks.

Ferrous hydroxide is usually made by adding alkali metals to a ferrous salt solution.

Hydroxides, because they are easily oxidized, must be used in an inert atmosphere (e.g. nitrogen, argon.

. Pure Fe(OH)2 is white, but when oxidized, it changes from green to dark green.

Ferrous hydroxide is unstable, and it is usually converted into iron hydroxide and reused in industry and life. There are three kinds of uses:

1. Ferric hydroxide colloids can be used to purify water;

2. Iron hydroxide production;

3. reducing water;

4. It is used to make pigments, drugs, catalysts, absorbents and arsenic antidotes.

Ferrous oxideand dilute nitric acidChemical equation. : 3FeO + 10Hno3 (rare) = 3Fe (No3) 3 + No + 5H2O.

Ferrous iron is reducing, dilute nitric acid is oxidizing.

The redox reaction undergoes between the two.

An oxidation-reduction reaction is a chemical reaction.

Before and after, there is a class of reactions in which the oxidation number of the element changes. The essence of a redox reaction is the gain or loss of electrons or the shift of shared electron pairs.

Ferrous oxide

Ferrous oxide is an inorganic substance.

Chemical formula FEO. It is one of the oxides of iron. It has a black powder in appearance, covalently bound to oxygen by iron in an oxidation state of +2 valence.

Its mineral form is galena (wüstite). Ferrous oxide is often confused with rust, but the main component of rust is hydrated iron oxide.

Ferrous oxide belongs to the cubic crystal system (similar to sodium chloride.

crystal structure), 6 oxygen atoms are attached around each iron atom to form an octahedral type coordination, and 6 iron atoms are also attached around each oxygen atom in the same situation. The reason for the appearance of non-integer compounds is that a small amount of divalent iron in FeO is replaced with ferric iron because it is easily oxidized to ferric, occupying tetrahedral voids in the crystal lattice.

fe(oh)2 + 2hno3 = fe(no3)2 + 2h2ofe(oh)2 + 2h+ =fe2+ +2h2o

Hello, I'm very happy to answer for you. Sodium nitrate is a neutral salt, iron hydroxide is a base, and it does not react 2NaOH + Fe (NO3) 2 = Fe (OH) 2 + 2nano3, where Fe (OH) generates finch imitation kinox ferrous hydroxide and sodium nitrate.

Nitric acid has strong oxidizing properties, which can oxidize ferrous oxide to produce the most advanced nitrate (ferric nitrate) of iron, and nitric acid is reduced to nitrogen oxides.

Dilute nitric acid produces nitric oxide.

Concentrated nitric acid produces nitrogen dioxide, and the reaction equation is as follows:

dilute) = 3Fe (NO3) 3 + No (gas arrow) + 5H2O concentrate) = Fe (NO3) 3 + NO2 (gas arrow) + 2H2O

Summary. The two do not react, it is turbid, although it does not react, but the ferrous hydroxide itself is a white insoluble solid in water, but because it is easily oxidized by oxygen in the air, the suspended solids of the mixture will quickly turn gray-green, and eventually turn reddish-brown. Sodium nitrate is a type of inorganic salt with the chemical formula nano3, a white solid powder, also known as Chilean saltpeter or Peruvian saltpeter (less common).

The world's largest sodium nitrate mine is located in the Atacama Desert in Chile. Sodium nitrate is oxidizing and can react with lead to produce sodium nitrite and lead oxide. Hydroiodic acid is also oxidized to iodine elemental matter at room temperature and nitric oxide is formed.

Still have any questions.

Ionic equation of ferrous hydroxide versus sodium nitrate?

No reaction occurs.

Unless it's nitric acid.

The redox reaction will occur.

Under alkaline conditions, there are few hydrogen ions, which cannot form nitric acid and does not oxidize ferrous ions.

Still have any questions.

Ferrous hydroxide eventually becomes iron hydroxide.

Valent iron becomes trivalent iron.

Yeah. Then sodium nitrate will be reduced.

It becomes sodium nitrite.

How does ferrous hydroxide become iron hydroxide? Excuse me.

What is the ionic equation of ferrous hydroxide vs sodium nitrate anyway?

You take a look. Thank you!
