How do you get barium paroxide?

Answer 1

Barium peroxide arises by the reversible absorption of O2 by barium oxide. The oxygen is released above 500°C.

[ 2 BaO2 ⇌ 2 BaO + O2 ]

Answer 2

Barium peroxide can be obtained by reacting barium oxide with hydrogen peroxide. The reaction typically occurs in an aqueous solution and the barium peroxide can be isolated through filtration and drying processes. It is important to handle barium compounds with proper safety precautions due to their toxic nature.
