Question

Potassium oxide dissolves in water dp we get hydrogen ?

Answer 1

2 K2O + 2 H2O gives 2 KOH + H2

Explanation:

Potassium metal reacts very rapidly with water to form a colourless solution of potassium hydroxide (KOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.
