Potassium amide is an inorganic compound with the chemical formula KNH2, i.e. it is composed of a potassium cation, and the conjugate base of ammonia. Like other alkali metal amides, it is a white solid that hydrolyzes readily.

Production

Potassium amide is produced by the reaction of liquid ammonia with potassium.[1]
