Hydronium perchlorate is aninorganic chemical compound with thechemical formula[H₃O]ClO₄. It is an unusualsalt due to it being a solid and stablehydronium salt. It consists of hydroniumcations[H₃O]⁺ andperchlorate anionsClO−4.

Production

[edit]

Hydronium perchlorate is produced by the reaction of anhydrousperchloric acid andwater in a 1:1molar ratio:^[2]

HClO₄ + H₂O → [H₃O]⁺ClO−4

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(II): transmetallation of the macrocycle withcopper(II) perchlorate yielded colorless crystals of hydronium perchlorate.^[1]

It can also be produced by the reaction of anhydrousnitric acid andperchloric acid.^[3]^{[clarification needed]}
