Characteristic
Iodic acid, HIO3. It is a white water-soluble solid. Its robustness contrasts with the instability of chloric acid and bromic acid. Iodic acid features iodine in the oxidation state +5 and is one of the most stable oxo-acids of the halogens.
Chemical formula:HIO3
Molar mass:175.91 g/mol
Appearance:White solid
Density:4.62 g/cm3, solid
Melting point:110 °C (230 °F; 383 K)
Solubility in water:269 g/100 mL (20 °C)
Acidity (pKa):0.75
Conjugate base Iodate
Magnetic susceptibility (χ):−48.0·10−6 cm3/mol
Application
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.
