Potassium oxide is an ionic compound: K2O Made up of ions K+ and O2-When added to the water the ... Alkaline solution will have a high pH such as pH 14.
Answer:
Good morning. Have a bangtastic day.
Explanation:
When potassium oxide reacts with water it gives potassium hydroxide as the product.
KOH is potassium hydroxide.
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.
Hope it helps.
