Thermodynamic properties of substances The solubility of the substances Periodic table of elements. Potassium cannot be found free because it is too reactive. If irritation persists, seek medical attention. Other important examples of basic oxides include FeO (iron oxide) and CaO (calcium oxide). He Potassium oxide , Also called dipotassium oxide, is an ionic salt of oxygen and potassium whose formula is K 2 O. KOH(s) --H2O(l)--> K+(aq) + OH-(aq) K2O(s) + H2O(l) --> 2K+(aq) + 2OH-(aq) Potassium hydroxide solid is hygroscopic, meaning that it "picks up" water from the vapor state. Cold water can be used. The substance is corrosive to the eyes, skin and respiratory tract, as well as being ingested.
