The equation for the reaction of potassium oxide with water.

Reaction equation: K2O + H2O = 2KOH.
To equalize the number of elements on the right and left, you need to put 2 in front of the hydroxide. On the left: 2 – potassium, 2 – hydrogen, 2 – oxygen. Right: all elements by 2.
Potassium oxide (K2O) is a basic oxide. When interacting with water, forms a base – potassium hydroxide (KOH).
