Applications

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.

Notes

Light sensitive. Incompatible with reducing agents, alcohols and organic materials.
