Iodine Reduction

Chemical Formula: I2
Present as: anion

Iodine is a chemical element with symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a lustrous, purple-black metallic solid at a standard conditions that sublimes readily to form a violet gas. The elemental form was discovered by the French chemist Bernard Courtois in 1811.
Iodine occurs in many oxidation states, including iodide (I−), iodate (IO−3), and the various periodate anions. It is the least abundant of the stable halogens, being the sixty-first most abundant element. It is even less abundant than the so-called rare earths. It is the heaviest essential element. Iodine is found in the thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities.
The dominant producers of iodine today are Chile and Japan. Iodine and its compounds are primarily used in nutrition and sometimes added to water as a disinfectant. Although not present as an ion, iodine complexes with strong base anion resin and is removed. Iodinated anion exchange resin is sometimes used as a controlled release form of iodine as a disinfectant for contaminated water supplies.

Iodate is a highly oxidized form of iodine where the iodine atom has a +5 valence. Iodate is used in titration methods for determination of various redox species.

Iodide preference by strong base anion resins increases with the size of the amine, tributylamine having roughly ten times the preference of trimethylamine.
