Most commonly, the term potassium sulfide refers loosely to this mixture, not the anhydrous solid. Another name for this inorganic compound is potassium hydrosulfide. This formula indicates that this compound is made up of twice as many sodium ions as sulfide ions. Structure, properties, spectra, suppliers and links for: Potassium sulfide, 1312-73-8. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions. Net Ionic: No Reaction 9. This means that the overall positive charge of the cations must be balanced by the overall negative charge of the anions.. Potassium sulfide is a chemical compound. So readily oxidized as to be pyrophoric in air [Bretherick 1979 p. 120]. Sodium sulfide, another ionic compound, has the formula \(\ce{Na_2S}\). Properties. Magnesiumoxide. ion. Its chemical formula is K 2 S. It contains potassium and sulfide ions. Molecular weight calculation: 39.0983*2 + 32.065 ›› Percent composition by element An ionic formula, like \(\ce{NaCl}\), is an empirical formula. The formula for potassium hydrogen sulfide is KHS. Name the following compound: MgO. Tools. Potassium sulfide is the inorganic compound with the formula K 2 S.The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH). One of the most important things to remember about ionic compounds is that they must be electrically neutral.. Molecular: cobalt(III) bromide + potassium sulfide Molecular: 2 CoBr3 (aq) + 3 K2S(aq) Co2S3 (s) + 6 KBr (aq) Total Ionic: 2 Co3+ (aq) + 6 Br¯ (aq) + 6 K+ (aq) + 3 S2-(aq) Co 2S3 (s) + 6 K + (aq) + 6 Br¯ (aq) Net Ionic: 2 Co3+ (aq) + 3 S2-(aq) Co 2S3 (s) 10.
