Which of the following oxide gives hydrogen peroxide on reaction with a dilute acid -

Answer:

Solution:

The correct answer is B.

Peroxides, like sodium peroxide ( $N a_{2} O_{2}$ ), react with dilute acids to produce hydrogen peroxide ( $H_{2} O_{2}$ ). The reaction is:

$N a_{2} O_{2} (s) + H_{2} S O_{4} (a q) ⟶ N a_{2} S O_{4} (a q) + H_{2} O_{2} (a q)$

Other oxides listed ( $P b O_{2}$ , $M n O_{2}$ , $T i O_{2}$ ) are dioxides and do not yield hydrogen peroxide under these conditions.
