Potassium Sulfide

Potassium Sulfide is the asleep admixture with the blueprint K2S. The colourless solid is rarely encountered, because it reacts readily with water, a acknowledgment that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH). Most commonly, the appellation potassium sulfide refers about to this mixture, not the anhydrous solid.
Structure
It adopts "antifluorite structure," which agency that the baby K+ ions absorb the tetrahedral (F−) sites in fluorite, and the beyond S2− centers absorb the eight-coordinate sites. Li2S, Na2S, and Rb2S accumulate similarly.
Potassium Sulfides are formed if atramentous crumb is austere and are important intermediates in abounding pyrotechnic effects, such as senko hanabi and some beam formulations.
