Analyze the nature of the reaction of sodium peroxide with water

The real process of the reaction between sodium peroxide and water is: the first step: the peroxide ions in the sodium peroxide are hydrolyzed to produce hydroxide ions and hydrogen peroxide, and the reaction releases a large amount of heat: Na2O22H2O

2naohh2o2o2(2-)2h2o

h2o22oh

The ion equation) Step 2: Hydrogen peroxide is unstable under alkaline and heated conditions and decomposes into water and oxygen: 2H2O2

2h2oo2↑

The above two equations are superimposed to obtain: 2Na2O2

4h2o2h2o2

4naoh2h2o2

2H2OO2 Subtracts the same substance on both sides of the equal sign to obtain: 2Na2O22H2O

4naoho2↑

Studied with isotope labeling, oxygen-18 radioactive atoms were labeled in sodium peroxide and the reaction equation was as follows:

2) So, the oxygen atom in sodium hydroxide does not come from sodium peroxide, but from water. When not marked, the water is the same, 1) The water before and after the medium size can cancel out 2, but after the marking, it can no longer be offset, such as (2).

Sodium peroxide. and water are two oxides, the former is more oxidizing, taking away the hydrogen in the water, and the remaining oxygen atoms become oxygen.

2na2o2+2h2o=4naoh+o2

Since you know that sodium peroxide is used as an oxidant and reducing agent, that is to say, half of the oxygen in sodium peroxide is used as a reducing agent, and generally as an oxidant, according to the equation, there are a total of four oxygen in sodium peroxide, and the two that are oxidized to generate oxygen, and the two that are reduced and the two oxygen elements in water to generate 4 hydroxide groups.

One of the principles of redox reaction is followed: the same element undergoes a redox valence state from both sides to the middle.

But not overpriced)

or from the middle to both sides.

Sodium peroxide. and the anti-clear chaos of waterEquationsYes: 2Na2O2+2H2O=4NaOH+O2.

The reaction between sodium peroxide and water first produces hydrogen peroxide, which is unstable and will decompose. na₂o₂+2h₂o=2naoh+h₂o₂；2Ho = 2 H O + O, reaction exothermic In an alkaline environment, sodium peroxide can oxidize +3 valence arsenic (AS) to +5 valence and +3 valence chromium (Cr) to +6 valence in the differential plexisphere.

Sodium peroxide.

Sodium peroxide is an inorganic compound with the chemical formula Na2O2, which is a beige powder or granule. Decomposes when heated to 460. Quickly absorbs moisture and carbon dioxide in the air.

Contact with organic matter can cause combustion or ** and should be stored tightly sealed. It is used to bleaching animal and plant fibers, feathers, animal bones, etc., as a printing and dyeing agent for fabrics, and a carbon absorber for air dioxide and cherry trees.

Store in a cool, dry and well-ventilated warehouse, away from fire and heat sources, the storage temperature does not exceed 35, the relative temperature does not exceed 75%, and the packaging is sealed. Pay attention to moisture and rain, should be stored separately from reducing agents, acids, alcohols, active metal powders, etc., do not mix storage, and the storage area should be equipped with suitable materials to contain leakage.

Sodium peroxide. and water reactionsChemical equations:2na2o2+2h2o=4naoh+o2↑。Sodium peroxide reacts with waterIonic equationsis 2Na2O2+2H2O=4Na++4OH-+O2.

Sodium peroxide is a white powder, but in most cases, sodium peroxide is a light yellow powder, what is sodium peroxide, in fact, sodium peroxide is one of the products of sodium combustion in oxygen or sodium in the air, sodium peroxide is relatively easy to deliquescent, corrosive, generally sodium peroxide is sealed and preserved.

The chemical equation for the reaction of sodium peroxide with water.

Sodium peroxide generally reacts with water and then with carbon dioxide.

The reaction is carried out, so the equation for the reaction of sodium peroxide with water is as follows:

2na2o2+2h2o=4naoh+o2;2naoh+co2=na2co3+h2o

The reaction is carried out in two steps: Na O + H O ===2NaOH + H O

Hydrogen peroxide. Unstable: 2h o ==2h o+o

The two are combined: 2Na O + 2H O==4NaOH + O (which is what we commonly use).

Sodium peroxide. It is one of the products of sodium combustion in oxygen or air, pure sodium peroxide is white, but the generally seen sodium peroxide is pale yellow, because a small amount of sodium superoxide (NAO, light yellow) is generated during the reaction. Sodium peroxide is easily deliquescent and corrosive, so it should be sealed and stored.

Sodium peroxide is strongly oxidizing.

It can be used to bleach textile products, straws, fibers, etc.

The chemical equation for the reaction of sodium peroxide and water is: 2Na2O2+2H2O=4NaOH+O2. The ionic equation for the reaction of sodium peroxide and water is 2Na2O2+2H2O=4Na++4Oh-+O2.

Sodium peroxide is a white powder, but in most cases, sodium peroxide is a light yellow powder, what is sodium peroxide, in fact, sodium peroxide is one of the products of sodium combustion in oxygen or sodium in the air, sodium peroxide is relatively easy to deliquescent, corrosive, generally sodium peroxide is sealed and preserved.

The chemical equation for the reaction of sodium peroxide with water.

Sodium peroxide generally reacts with water first and then with carbon dioxide, so the equation for the reaction of sodium peroxide with water is as follows:

2na2o2+2h2o=4naoh+o2;2naoh+co2=na2co3+h2o

The chemical equation for the reaction of sodium peroxide with water is: 2NaO + 2Ho = 4NaOH +O.

The actual reaction is that sodium peroxide first reacts with water to form sodium hydroxide and hydrogen peroxide, and the equation for the reaction is:

na₂o₂+2h₂o=2naoh+h₂o₂。

Then the hydrogen peroxide will be more and water and oxygen will be generated, and the chemical equation of the reaction is:

2Ho = 2Ho + O, the reaction is an exothermic reaction.

Redox reactions.

Sodium peroxide is both a reducing agent and an oxidizing agent.

VR 3D** Platform: Sodium Peroxide and Water Reaction.

Generally speaking, the reaction between metal peroxide and water is carried out in two steps: the first step is the metathesis reaction between metal peroxide and water to produce hydroxide and hydrogen peroxide; The second step is the decomposition reaction of hydrogen peroxide (because the reaction between metal peroxide and water is an exothermic reaction, and the thermal stability of hydrogen peroxide is poor, it is easy to decompose reaction). Take the reaction of sodium peroxide with water as an example.

Na2O2 2H2O 2NaOH H2O2, 2H2O2 2H2O O2, so the solution obtained after the reaction of metal peroxide with water usually contains H2O2 and makes the solution have strong oxidation.
