Question

define preparation of hydrogen peroxide from Alkali metals?

​

Answer 1

Answer:

Most alkali metal peroxides can be synthesized directly by oxygenation of the elements. Lithium peroxide is formed upon treating lithium hydroxide with hydrogen peroxide: 2 LiOH + H2O2 → Li2O2 + 2 H2O. Barium peroxide is prepared by oxygenation of barium oxide at elevated temperature and pressure.

Most alkali metal peroxides can be synthesized directly by oxygenation of the elements. Lithium peroxide is formed upon treating lithium hydroxide with hydrogen peroxide:$\bold{2LiOH+H_2O_2}$ ⇒ $\bold{Li_2O_2+2H_2O}$ Barium peroxide is prepared by oxygenation of barium oxide at elevated temperature and pressure.
