Question

Suggest the pH of the solution made when potassium oxide dissolves in water.

Answer 1

Potassium oxide (K₂O): ionic compound.

Reaction:

K₂O + H₂O →2KOH

KOH = strong base, pH>7

Answer 2

Answer:

Since KOH is a strong base, the solution completely ionizes into K+ and OH- when in water. The reaction KOH --> K+ + OH- takes place. The concentration of [ OH- ] can then be used to calculate the pOH of the solution. pH = 14 - pOH = 14 - 1.48 = 12.52
