Hydronium perchlorate is an inorganic chemical compound with the chemical formula [H
3O]ClO
4. It is an unusual salt due to it being a solid and stable hydronium salt. It consists of hydronium cations [H
3O]+
and perchlorate anions ClO−
4.
Production
Hydronium perchlorate is produced by the reaction of anhydrous perchloric acid and water in a 1:1 molar ratio:[2]
- HClO
4 + H
2O → [H
3O]+
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 with copper(II) perchlorate yielded colorless crystals of hydronium perchlorate. [1]
It can also be produced by the reaction of anhydrous nitric acid and perchloric acid.[3]
