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.

Application


  • Insights into the Chemistry of Iodine New Particle Formation: The Role of Iodine Oxides and the Source of Iodic Acid.: This research provides an in-depth analysis of iodic acid′s role in new particle formation, highlighting the impact of iodine oxides in atmospheric chemistry processes (Gómez Martín et al., 2022).


  • Ion Mobility-Mass Spectrometry of Iodine Pentoxide-Iodic Acid Hybrid Cluster Anions in Dry and Humidified Atmospheres.: The study uses ion mobility-mass spectrometry to examine the properties of iodine pentoxide-iodic acid hybrid clusters under varying atmospheric conditions, providing insights for analytical chemistry applications (Ahonen et al., 2019).


  • Colour reactions of iodic acid as reagent for identifying drugs by thin-layer chromatography.: This older study explores the use of iodic acid for drug identification in thin-layer chromatography, underscoring its utility in analytical methods (Cavazzutti et al., 1983).
