Hydronium perchlorate
Hydronium perchlorate is an inorganic [chemical compound] with the chemical formula. It is an unusual salt due to it being a solid and stable hydronium salt. It consists of hydronium cations and perchlorate anions.
Production
Hydronium perchlorate is produced by the reaction of anhydrous perchloric acid and water in a 1:1 molar ratio:A more analytically reliable method was reported using the macrocyclic Schiff base of sodium 2,6-diformyl-4-methylphenolate and 2,6-diformyl-4-methylphenol as a chelating agent to sequester Cu: transmetallation of the macrocycle with copper(II) perchlorate yielded colorless crystals of hydronium perchlorate.
It can also be produced by the reaction of anhydrous nitric acid and perchloric acid.
