Potassium sulfide is an inorganic compound with the formula K2S. 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 … Visa mer It adopts "antifluorite structure," which means that the small K ions occupy the tetrahedral (F ) sites in fluorite, and the larger S centers occupy the eight-coordinate sites. Li2S, Na2S, and Rb2S crystallize similarly. Visa mer 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 … Visa mer • Liver of sulfur Visa mer Potassium sulfides are formed when black powder is burned and are important intermediates in many pyrotechnic effects, such as Visa mer Webb29 jan. 2024 · The ionic form of this reaction is: 2 Na + (aq) + 2 Cl - (aq) + Cu 2+ (aq) + SO 42- (aq) → 2 Na + (aq) + SO 42- (aq) + CuCl 2 (s) The sodium ions and sulfate ion are the spectator ions in this reaction. They appear unchanged in both the product and reactant side of the equation.
