Is potassium sulfide a solid or a mixture?
The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH). Most commonly, the term potassium sulfide refers loosely to this mixture, not the anhydrous solid.

Is potassium ionic or molecular?
ionicIn the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, that is easily removed to create an ion with a positive charge – a cation, that combines with anions to form salts. Potassium in nature occurs only in ionic salts.

Structure
It adopts "antifluorite structure," which means that the small K + ions occupy the tetrahedral (F −) sites in fluorite, and the larger S 2− centers occupy the eight-coordinate sites. Li 2 S, Na 2 S, and Rb 2 S crystallize similarly.
Use in fireworks
Potassium sulfides are formed when black powder is burned and are important intermediates in many pyrotechnic effects, such as senko hanabi and some glitter formulations.

Synthesis and reactions
It can be produced by heating K2SO4 with carbon (coke):
K2SO4 + 4 C → K2S + 4 CO
In the laboratory, pure K2S may be prepared by the reaction of potassium and sulfur in anhydrous ammonia.
Sulfide is highly basic, consequently K2S completely and irreversibly hydrolyzes in water accordin…
