. There are three oxides of potassium—a suboxide, aprotoxide, and a peroxide; K2 O, KO, and KOz. Suboxide of Potassium, IT20=869 is formed by heating potassium in a limited amount ofair. It takes fire when heated, and is converted by wa-ter into potassa, hydrogen being evolved. What interferes with… … HYDRATED OXIDE OF POTASSIUM. 315 Protoxide of Potassium, K0=41, is made by heating one atom of potassium with one ofhydrate of potassa, K+KO, IIO=.2KO+H. Hydrated Oxide of Potassium, KO, HO=:56, is best procured by boiling two parts of pure carbonateof potassa with twenty of water, and, having…
