Potassium hydrosulfide

Potassium hydrosulfide is an inorganic compound with the formula KSH.

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.

Their structure is however complicated by the non-spherical symmetry of the SH− anions, but these tumble rapidly in the solid.

[2] The addition of sulfur gives dipotassium pentasulfide.

E.g. chlorine gas Flammability 2: Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Flash point between 38 and 93 °C (100 and 200 °F). E.g. diesel fuel Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
