| General description: | 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. |
