Potassium hydrosulfide is the inorganic compound with the formula KHS. This colourless salt consists of the cation K and the bisulfide anion [SH]. It is the product of the half-neutralization of hydrogen sulfide with potassium hydroxide. The compound is used in the synthesis of some organosulfur compounds. It is prepared by neutralizing aqueous KOH with H2S. Aqueous solutions of potassium sulfide consist of a mixture of potassium hydrosulfide and potassium hydroxide.
