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 Potassium bisulfate Potassium bisulfate, is an inorganic compound with the chemical formula KHSO and is the potassium acid salt of sulfuric acid. Mercallite, the mineralogical form of potassium bisulfate, occurs very rarely. Misenite is another, more complex, form of potassium bisulfate. Potassium bisulfate is prepared by neutralizing sulfuric acid with an equal molar amount of a potassium containing base, for example potassium hydroxide: Potassium bisulfate is also formed by the union of sulfuric acid with potassium sulfate: Potassium bisulfate is also the main by-product in the production of nitric acid from potassium nitrate and sulfuric acid: Thermal decomposition of potassium
