Solution

The correct option is D (a) and (b) above.
Laboratory method: Hydrogen peroxide is prepared from barium peroxide.
By the action of dilute sulphuric acid. A paste of hydrated barium peroxide. $(B a O_{2} .8 H_{2} O)$ is prepared in ice – cold water and then added slowly to an ice-cold solution of $20 % H_{2} S O_{4}$
$B a O_{2} .8 H_{2} O + H_{2} S O_{4} \to B a S O_{4} ↓ + H_{2} O_{2} + 8 H_{2} O$

Prepared by Merck’s process: Adding calculated amounts of sodium peroxide to ice cold dilute (20%) solution of $H_{2} S O 4$
$N a_{2} O_{2} + H_{2} S O_{4} \to N a_{2} S O_{4} + H_{2} O_{2}$
