1. What Are The Physical And Chemical Properties Of Sodium Peroxide?

Sodium peroxide is a yellowish-white solid with a melting point of 675°C. It is highly reactive and can spontaneously ignite in contact with organic materials such as oils and greases. Sodium peroxide is soluble in water, and upon dissolution, it reacts vigorously to produce hydrogen peroxide and sodium hydroxide.

Chemically, sodium peroxide is an oxidizing agent and can react violently with reducing agents or combustible materials such as sulfur, phosphorus, and metals. It is also used as a source of oxygen in chemical reactions and has applications in the production of various chemicals, including dyes, pharmaceuticals, and pesticides.

When exposed to air, sodium peroxide can absorb moisture and carbon dioxide, which may result in the release of heat and the formation of sodium carbonate. Therefore, it should be stored in a dry environment and handled with care due to its reactivity and potential hazards.
