Useful:

• Chemical Classes: Toxic Gases & Vapors -> Acids, Inorganic
• Canonical SMILES: OI(=O)=O
• Physical Properties: White stable crystalline solid; rhombohedral crystals; occurs in two forms: the normal HIO3, and pyroiodic acid HI3O8.
• Uses: Aqueous solutions of iodic acid serve as strong oxidizing agents. The acid also is used in redox titrations. Iodic acid is used in analytical chemistry laboratories to standardize solutions of both weak and strong bases using methyl red or methyl orange as the indicator. It acts as a key starting material to synthesize sodium or potassium iodate, thereby increasing the iodine content of salt. A strong acid in analytical chemistry.
• Physical properties: Iodic acid, HIO3, can be obtained as a white solid. It dissolves in water very well, but it also exists in the pure state, as opposed to chloric acid or bromic acid. Iodic acid contains iodine in the oxidation state+5 and it is one of the most stable oxo-acids of the halogens in its pure state. When iodic acid is carefully heated, it dehydrates to iodine pentoxide. On subsequent heating, the iodine pentoxide further decomposes, giving a mixture of iodine, oxygen and lower oxides of iodine. Iodic acid can be produced by oxidizing I2 with chlorine in an aqueous solution. Iodic acid can be used to synthesize sodium or potassium iodate salts (which are used in salt as a source of iodine in the human body.
