Question

$$H_{2}O_{2}$$ is always stored in black bottles because:


A
It is highly unstable
loader
B
Its enthalpy of decomposition is high
loader
C
It undergoes autooxidation on prolonged standing
loader
D
None of these
loader

Solution

The correct option is C It undergoes autooxidation on prolonged standing
On prolonged standing, hydrogen peroxide undergoes auto oxidation or disproportionation. $$2H_2O_2 \rightarrow 2H_2O + O_2$$ Hence, hydrogen peroxide is always stored in black bottles which cuts off the light and suppresses the auto oxidation.
