Question

Potassium oxide when reacted with water results in the formation of the same product as formed by potassium on reaction with water. Name the product formed.

Answer 1

Potassium when reacted with water produces potassium hydroxide and hydrogen gas.

$K+H_{2}O\to KOH+H_2$
Potassium oxide also reacts with water to form potassium oxide.

$K_{2}O+H_{2}O\to KOH$
KOH is the common product formed in both reactions.
