Descripción general

General description It is hygroscopic, readily soluble in water (resulting in an alkaline solution), insoluble in alcohol, and loses two molecules of water of crystallization upon heating to 180°C, and completely loses water upon heating to 300°C. Its solubility in 100g of water at 25°C is 187g. A 1% aqueous solution has a pH of 10.2. Potassium pyrophosphate possesses all the properties of other condensed phosphates. Applications include analytical reagents, hydrogen peroxide stabilizers, electroplating, and soap fillers.
