When potassium superoxide is dissolved in water, the products obtained are

A
KOH and $H_{2} O_{2}$
Correct answer
B
KOH, $H_{2} O_{2}$ and $O_{2}$
C
KOH and $O_{2}$
D
KOH, $H_{2} O_{2}$ and $O_{3}$

Solution

When potassium superoxide is dissolved in water, KOH,

H_{2} O_{2}

and

O_{2}

are formed

2 K O_{2} + 2 H_{2} O \to 2 K O H + H_{2} O_{2} + O_{2}

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