Potassium iodate is a strong oxidizing agent that can be used to assay several pharmaceutical substances through titration. It reacts quantitatively with both iodides and iodine. The titrations can be performed in the presence of organic acids, alcohols, and other organic substances. The oxidation-reduction reactions with potassium iodate produce iodine monochloride in strong hydrochloric acid. Some applications of potassium iodate titrations include the determination of potassium iodide, weak iodine solutions, aqueous iodine solutions, sodium diatrizoate, iodized oil fuel injection, mercury chloride, and hydralazine hydrochloride and injection.
