Does hydrogen peroxide produced by the hydrolysis of sodium peroxide decompose immediately?

I don't think so, first of all, sodium peroxide.

In water, it immediately reacts with water, and the first step of hydrolysis is to turn into sodium hydroxide.

and hydrogen peroxide, but you must know that sodium peroxide is exothermic when dissolved in water, and it will release a lot of heat, so hydrogen peroxide immediately decomposes because sodium peroxide is dissolved in water and exothermic. But if you take phenolphthalein.

Add it to the mixed solution of sodium peroxide and water, and you will see that the solution turns red first and then fades, which means that the hydrogen peroxide in the solution is in the solution.

There are still some, but there are relatively few, so it is not suitable for preparation.

As for how long you say it will be stable, it depends on the temperature, if the temperature is relatively high, then there will be more hydrogen peroxide decomposed. In addition, hydrogen peroxide will decompose when it encounters any metal magazine, so it is more difficult to exist stably.

The reason why it is written in the book is that when you experiment, as soon as the sodium peroxide dissolves in water, it begins to exothermic, and after hydrolysis, the hydrogen peroxide decomposes at once due to the high temperature, and it is almost invisible. That's how a lot of the reaction in the book is.

Target. Do you remember the reaction in which aluminum dissolved in sodium hydroxide released hydrogen? In fact, it is also a compound reaction, the first step is the reaction of aluminum and water, and then the reaction of aluminum and sodium hydroxide, but it is combined in the book, as for the principle, as long as you are clear.

No, remember to use manganese dioxide to catalyze hydrogen peroxide decomposition.

No, hydrogen peroxide is most stable at pH = and does not decompose when it is not heated or illuminated. However, it is very easy to decompose under alkaline conditions.

The reaction between carbon dioxide and sodium hydroxide is not a metathesis reaction, which is defined as a reaction in which two compounds exchange components with each other to form two other compounds. The reaction between carbon dioxide and sodium hydroxide does not exchange components with each other, so it does not belong to the metathesis reaction.

The reaction equation of carbon dioxide and sodium hydroxide is: CO2+2NaOH=Na2CO3+H2O. Obviously, CO2 does not exchange this component with NaOH, so it is not a metathesis reaction.

The metathesis reaction is a reaction in which two compounds exchange components with each other to produce two other compounds. The essence of the metathesis reaction is that the two substances that undergo the metathesis reaction exchange ions in the aqueous solution, and combine into the precipitation of the hard-to-ionize substance, gas or weak meng Kai group electrolyte (most commonly water), so that the ion concentration in the solution is reduced, and the chemical reaction is carried out in the direction of the reduction of ion concentration. It can be abbreviated as ab+cd=ad+cb.

Sodium peroxide. The chemical equation for reacting with water to produce hydrogen peroxide.

The reaction is carried out in two steps: Na O +H O===2NaOH+H O Hydrogen peroxide is unstable: 2H O ==2HO+O The two are combined: 2Na O +2HO==4NaOH+O (which is what we commonly use).

The first step in the reaction between sodium peroxide and water is to produce sodium hydroxide and hydrogen peroxide

Na2O2 2H2O === 2NaOh H2O2 The second step is the decomposition of hydrogen peroxide into water and oxygen:

2H2O2 === 2H2O O2 will be 2 , and the total reaction chemistry equation is:

2 Na2O2 2H2O === 4NaOH O2 In particular, the reaction products of the first step are extremely unstable, and they are basically instantaneously converted into the second step.

Sodium peroxide reacts with water to produce sodium hydroxide and oxygen, but does not produce hydrogen peroxide, and its reaction equation is:

na2o2 +h2o = 2naoh + 1/2o2

Sodium peroxide reacts with acid to produce hydrogen peroxide, and its reaction equation is: Na2O2 +2HCl = 2NaCl + H2O2

The chemical equation for the reaction of sodium peroxide and water to produce hydrogen peroxide (hydroperoxide) is as follows:

2 na2o2 + 2 h2o → 4 naoh + h2o2

In this reaction, sodium peroxide (Na2O2) and water (H2O) react to produce sodium hydroxide (NaOH) and hydrogen peroxide (H2O2). Hydrogen peroxide is a strong oxidizing agent with bleaching and disinfecting properties.

I'll take this: NA2O2+2H2O=H2O2+2NAOH

2H2O2 = catalyst = 2H2O+O2 (gas symbol).

Thank you! : This is the principle of reaction, because the reaction is exothermic, so hydrogen peroxide decomposes to produce oxygen and water.

The reaction of sodium peroxide (Na2O2) with water (H2O) to form hydrogen peroxide (H2O2) is not a redox reaction, but an oxidation reaction.

Sodium peroxide is an oxidizing perturbator that oxidizes hydrogen atoms in water into hydroxide ions (oh-). This is a one-way reaction in which sodium peroxide is oxidized to hydrogen peroxide.

Sodium peroxide: 2Na2O2 + 2H2O 4NaOH + H2O2 If it is a redox reaction, there needs to be a substance that is an oxidizing agent and the other is a reducing agent, and they transfer electrons to each other, and after the reaction, both substances change the electronic structure, and only sodium peroxide is oxidized in this reaction.

1) Sodium peroxide cavity and water reaction: Na2O2 + 2H2O = 2NaOH + H2O2

2) There is no valency change in the reaction process, and there is no electron transfer without redox reaction!

3) Na+[o-o]Na+ = H-O-O-H peroxy structure has not changed!

The essence of the reaction between sodium peroxide and water is that it becomes H2O2, and the generated H2O2 is decomposed to form O2This can be proven experimentally.

Drop water into Na2O2, excess water, and then add phenolphthalein solution dropwise. Reaction phenomenon: first turn red and then dull and fade.

Chemical principle: Na2O2+2H2O=H2O2+2NaOH---12H2O2=2H2O+O2( )21 formula*2+2 formula, the total reaction formula: 2Na2O+2H2O=4NaOH+O2( )r Because of the generated NaOH solution, the Hui cover turns red when it encounters phenolphthalein; Because of the formation of H2O2, H2O2 has strong oxidizing properties, decomposes to generate free oxygen, bleaches and fades colored substances.

Therefore, sodium peroxide reacts with water to form hydrogen peroxide, which also forms oxygen precursors.

Guess: We guess that hydrogen peroxide contains hydrogen, oxygen, and water.

Experimental idea: heat hydrogen peroxide to decompose hydrogen peroxide after receiving energy. (But this time we don't use the heating method.)

Experimental materials: manganese dioxide (mnO2), hydrogen peroxide, H2O2, Erlenmeyer flask, rubber catheter.

Procedure: Pour a little hydrogen peroxide into an Erlenmeyer flask, quickly add manganese dioxide, and close the stopper. The gas produced by hydrogen peroxide and manganese dioxide is collected in the bottle by drainage, and the cap is quickly closed to collect the gas.

Result: A small wooden stick with a spark. Put it in a bottle with gas.

A small wooden cabinet on Mars can be found on fire. We fed and guessed if the gas was hydrogen or oxygen. A mixture of boiling manganese dioxide and hydrogen peroxide, we guess is water.

limb or. Conclusion: Sodium peroxide can be decomposed.

1. When a small amount of SO is introduced into sodium hypochlorite solution, the following reaction occurs:

so₂ +3naclo + h₂o = 2hclo + na₂so₄ +nacl

So +3Clo +H O = 2HCl + So Cl 2, and the following reaction occurs when excess SO is introduced into sodium hypochlorite:

so₂ +2naclo + h₂o = nahso₄ +nacl + hcl

so₂ +2 clo⁻ +h₂o = so₄²⁻2h⁺ +2 cl⁻<>

With water, but only an intermediate product, because the reaction of sodium peroxide with water will release a lot of heat, so that the intermediate product hydrogen peroxide decomposes.

The main process is:

Sodium peroxide + water = sodium hydroxide + hydrogen peroxide.

Hydrogen peroxide is decomposed into water and oxygen when heated.

Sodium peroxide is dissolved in water to produce sodium hydroxide and hydrogen peroxide. The reaction formula is as follows:

na2o22h2o===

2naohh2o2

No, sodium peroxide reacts with water to produce only sodium hydroxide and oxygen. The reaction equation is: 2Na2O2+2H2O=4NaOH+O2

Think of sodium peroxide as a salt of hydrogen peroxide. Hydrolysis of strong and weak salts produces hydrogen peroxide.

The essence of the reaction between sodium peroxide and water is that it becomes H2O2, and the generated H2O2 is decomposed to form O2

This can be proven experimentally. Drop water into Na2O2, excess water, and then add phenolphthalein solution dropwise.

Reaction phenomenon: first reddening and then fading.

Chemical principle: Na2O2+2H2O=H2O2+2NaOH---1

2h2o2=2h2o+o2(^)2

1 formula * 2 + 2 formula, then the total reaction formula: 2Na2O+2H2O=4NaOH+O2( ).

Because of the NaOH solution generated, it turns red when exposed to phenolphthalein; Because of the formation of H2O2, H2O2 has strong oxidizing properties, decomposes to generate free oxygen, bleaches and fades colored substances.

Therefore, sodium peroxide reacts with water to form hydrogen peroxide, which also produces oxygen.

Sodium peroxide reacts with water to produce sodium hydroxide and oxygen.

The first step in the reaction between sodium peroxide and water is to produce sodium hydroxide and hydrogen peroxide

na2o2＋2h2o
