What would be the pH of a reaction between potassium oxide and water?
Potassium oxide is an ionic compound: K2O Made up of ions K+ and O2-When added to the water the oxide reacts to form a hydroxide compound.K2O + H2O = 2KOHKOH is made of K+ and OH- ions. The high level of hydroxide ions (OH-) makes the solution alkaline.Alkaline solution will have a high pH such as pH 14
