The chemical equation for the reaction between sodium peroxide and water is 2Na2O2+2H2O=4NaOH+O2↑.
I. Ionic equations
The ionic equation for the reaction between sodium peroxide and water is 2Na2O2+2H2O=4Na++4OH-+O2↑.
II. Reaction Explanation
The reaction between sodium peroxide and water is a chemical reaction in which sodium peroxide (Na2O2) reacts with water (H2O) to form sodium hydroxide (NaOH) and oxygen (O2).
During the reaction, sodium peroxide breaks down into two sodium ions (Na+) and one peroxide ion (O2-). Hydrogen ions (H+) in the water molecule combine with the peroxide ion to form hydroxide ions (OH-). These hydroxide ions combine with the remaining sodium ions to form sodium hydroxide (NaOH), while releasing oxygen.
Three, the reaction phenomenon
Sodium peroxide and water react to produce hydrogen peroxide, alkaline hydrogen peroxide is unstable, will decompose, there is a gas released, and a lot of heat. The production of sodium hydroxide is not a phenomenon because it cannot be observed unless phenolphthalein is added to the water beforehand (at which point the water containing phenolphthalein can be observed to turn red).
Four, the type of reaction and the acidity of the solution after the reaction
This reaction is an exothermic reaction, that is, the reaction process will release heat. Also, the solution after the reaction is alkaline due to the generation of sodium hydroxide.
Uses of the reaction between sodium peroxide and water:
I. Bleach
Ferric hydroxide is a strong alkali that can be used as a bleaching agent. It removes stains and coloring from clothing, paper, wood and other materials, making them whiter.
Two, oxidizer
Oxygen is a strong oxidizing agent that can be used in many chemical reactions. It can promote combustion reactions to accelerate the oxidation process of organic matter.
Three, disinfectant
Sodium hydroxide has a bactericidal and disinfectant effect, and can be used to clean and disinfect medical equipment, laboratory apparatus, food processing equipment and so on.
Four, waste water treatment
Sodium hydroxide produced by the reaction between sodium peroxide and water can be used for waste water treatment. It can neutralize acidic wastewater, adjust the pH value of wastewater, and promote the oxidative decomposition of organic matter in wastewater.
V. Chemical synthesis
Sodium peroxide can be used as an oxidizing agent in organic synthesis reactions. It can participate in the oxidation of alcohols, ketone synthesis and other reactions.
