Sodium peroxide in contact with moist air turns white due to formation of:

  • A
    $\mathrm{Na}_{2} \mathrm{CO}_{3}$
  • B
    $\mathrm{Na}_{2} \mathrm{O}$
  • Correct answer
    C
    $\mathrm{NaOH}$
  • D
    $\mathrm{NaHCO}_{3}$

Solution

$\mathrm{Na}_{2} \mathrm{O}_{2}+\mathrm{H}_{2} \mathrm{O} \longrightarrow 2 \mathrm{NaOH}+\frac{1}{2} \mathrm{O}_{2}$

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