Question

Give the reaction when sodium peroxide dissolved in water

Answer 1

Water is an inorganic, translucent, tasteless, odourless, and almost colourless chemical element that is the primary component of the Earth's hydrosphere and other recognised living organisms' fluids.
Sodium peroxide is a yellowish solid that is formed when sodium is burned in an environment of so much oxygen. It's a strong base. There are many hydrates and peroxyhydrates of this metal peroxide.

Complete answer:

Sodium peroxide is a yellowish solid that is formed when sodium is burned in an environment of so much oxygen. It's a strong base. There are many hydrates and peroxyhydrates of this metal peroxide.
The reaction when sodium peroxide dissolves in water can be given as
${N{a_2}{O_2}{\text{ }} + {\text{ }}2{H_2}O{\text{ }}\xrightarrow[{}]{}{\text{ }}2NaOH{\text{ }} + {H_2}{O_2}}$
There are two products made, Hydrogen Peroxide and Sodium Hydroxide
The inorganic compound sodium hydroxide, also known as lye or caustic soda, has the formula NaOH. It's a dense ionic complex made up of sodium cations and hydroxide anions that's white in colour.
The chemical compound hydrogen peroxide has the formula H₂O₂. It's a very pale blue liquid that's much more viscous than water in its purest nature. It's a bleaching agent, an oxidizer, and an antiseptic.
