Powdered potassium sulfide anhydrous. Potassium sulfide is an 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). Most commonly, the term potassium sulfide refers loosely to this mixture ...

Tie up loose ends. Two Lewis structures must be drawn: Each structure has one of the two oxygen atoms double-bonded to the nitrogen atom. The second oxygen atom in each structure will be single-bonded to the nitrogen atom. Place brackets around each structure, and add the charge (−) to the upper right outside the brackets.

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. The compound is used in the synthesis of some organosulfur compounds. [1]
Potassium oxide is produced from the reaction of oxygen and potassium; this reaction affords potassium peroxide, K 2 O 2. Treatment of the peroxide with potassium produces the oxide: [5] K 2 O 2 + 2 K → 2 K 2 O. Alternatively and more conveniently, K 2 O is synthesized by heating potassium nitrate with metallic potassium: 2 KNO 3 + 10 K → 6 ...
