Solution

Liquid sodium metal is used as a coolant (heat-transfer medium) in a nuclear reactor.

Potassium is used in the preparation of potassium hydroxide which is used in the manufacture of soft soap.

Potassium nitrate is used in ceramics, colour TV tubes, fluorescent light tubes and explosive stearate.

Potassium superoxide is used in breathing apparatus, submarine and space capsules.
$K O_{2}$ reacts directly with $C O$ and $C O_{2}$ producing $O_{2}$ as follows:

$2 K O_{2} + C O \to K_{2} C O_{3} + O_{2}$
$4 K O_{2} + 2 C O_{2} \to 2 K_{2} C O_{3} + 3 O_{2}$
$4 K O_{2} + 4 C O_{2} + 2 H_{2} O \to 4 K H C O_{3} + 3 O_{2}$
