Beschreibung

Allgemeine Beschreibung

Iodic acid is the hydrated form of I₂O₅. Reaction of iodic acid with hydrogen iodide has been described by electrolytic dissociation theory. Combustion of mixture of chromic, iodic, sulfuric and phosphoric acids has been proposed. Its Raman spectra have been recorded. Vibrational assignment of IO₃^- has been evaluated.
