Solution

When aqueous $K O_{2}$ solution reacts with $C O_{2}$ , $O_{2}$ is formed and thus, $K O_{2}$ is used in submarines.
$4 K O H + 2 C O_{2} ⟶ K_{2} C O_{3} + 3 O_{2}$
Potassium superoxide is used as a $C O_{2}$ scrubber, $H_{2} O$ dehumidifier and $O_{2}$ generator in rebreathers, spacecraft, submarines and spacesuit life support systems.
