The oxide that gives $\mathrm{H}_2 \mathrm{O}_2$ on treatment with dilute acid is

  • A
    $\mathrm{PbO}_2$
  • B
    $\mathrm{MnO}_2$
  • Correct answer
    C
    $\mathrm{Na}_2 \mathrm{O}_2$
  • D
    $\mathrm{TiO}_2$

Solution

Peroxides give hydrogen peroxide, on treatment with dilute acids. Hence, only sodium peroxide $\left(\mathrm{Na}_2 \mathrm{O}_2\right)$ will give $\mathrm{H}_2 \mathrm{O}_2$.

Hence, the correct answer is option: 'C'.
