Potassium hydroxide nomenclature

Peroxomonosulfa.tes, When oleum is mixed with hydrogen peroxide and the mixture is partially neutralized by potassium hydroxide, a triple salt [37222-66-5] crystallizes out. In the old nomenclature, the formula for the triple salt was written as if it comprised three salts 2... 

Bases that contain hydroxide ion are named very simply by the rules of nomenclature for ionic compounds. The name consists of the name of the metal followed by hydroxide. For example, LiOH is lithium hydroxide, KOH is potassium hydroxide, and Mg(OH)2 is magnesium hydroxide. 

In the days of alchemy and the phlogiston theory, no system of nomenclature that would be considered logical ia the 1990s was possible. Names were not based on composition, but on historical association, eg, Glauber s salt for sodium sulfate decahydrate and Epsom salt for magnesium sulfate physical characteristics, eg, spirit of wiae for ethanol, oil of vitriol for sulfuric acid, butter of antimony for antimony trichloride, Hver of sulfur for potassium sulfide, and cream of tartar for potassium hydrogen tartrate or physiological behavior, eg, caustic soda for sodium hydroxide. Some of these common or trivial names persist, especially ia the nonchemical Hterature. Such names were a necessity at the time they were iatroduced because the concept of molecular stmcture had not been developed, and even elemental composition was incomplete or iadeterminate for many substances.
