Potassium oxide hydroxide. It is deliquescent and will absorb water from the atmosphere, initiating this vigorous reaction. The chemical formula KO (or simply 'K') is used in several industrial contexts: the N-P-K numbers for fertilizers, in cement formulas, and in glassmaking formulas. Potassium oxide is often not used directly in these products, but the amount of potassium is reported in terms of the KO equivalent for whatever type of potash was used, such as potassium carbonate. For example, potassium oxide is about 83% potassium by weight, while potassium chloride is only 52%. Potassium chloride provides less potassium than an equal amount of
Potassium bisulfate bisulfate forms potassium pyrosulfate and water: Temperatures above 600 °C further decompose potassium bisulfate to potassium sulfate and sulfur trioxide: Aqueous solutions of potassium bisulfate behave as two separate, uncombined compounds, KSO and HSO. Adding ethanol to the solution precipitates out potassium sulfate. Potassium bisulfate is commonly used to prepare potassium bitartrate for winemaking. Potassium bisulfate is also used as a disintegrating agent in analytical chemistry or as a precursor to prepare potassium persulfate, a powerful oxidizing agent. Potassium bisulfate Potassium bisulfate, is an inorganic compound with the chemical formula KHSO and is the potassium acid salt of sulfuric acid.
