When a rapid stream of CO2 is bubbled through solution of BaO2 in ice-cold water, H2O2 and BaCO3 are produced.

Q. $H_{2} O_{2}$ is prepared in the laboratory when -

$M n O_{2}$ is added to dilute cold $H_{2} S O_{4}$

$B a O_{2}$ is added to $C O_{2}$ bubbling through cold water

$P b O_{2}$ is added to an acidified solution of $K M n O_{4}$

$N a_{2} O_{2}$ is added to boiling water

When a rapid stream of $C O_{2}$ is bubbled through solution of $B a O_{2}$ in ice-cold water, $H_{2} O_{2}$ and $B a C O_{3}$ are produced.
