Property: Potassium Bicarbonate is colorless and transparent crystal. The relative density is 2.17. It is stable in the air. It is soluble in water, forming a slightly alkaline solution, but insoluble in alcohol. The solution can not react with magnesium salt yielding precipitate of alkaline salt. It begins to decompose at 100°C and completely decomposes and turns into Potassium Carbonate losing carbon dioxide and water at 200°C.
