Potassium iodide

Potassium Iodide: CAS: 7681-11-0, Molecular formula KI . Mwt. 166 gm/mol is an inorganic salt of Iodine ,available in white crystalline powder form. Due to its Ionic form K+ I- , and iodide ion being a mild reducing agent , it can be easily oxidized to Iodine by powerful oxidizing agent like chlorine. With elemental iodine it forms I3 ( tri iodide) , the salts of tri iodide are highly water soluble. On long exposure to air Potassium Iodide becomes yellow due to liberation of Iodine . Potassium Iodide is more readily soluble in water. The solubility in water increases with the increase in temperature ie. ( 140 gms. /100 ml @ 20 oc, 206 gms/ 100 ml @ 100 oc,) . It is slightly soluble in ether, ammonia. It absorbs water less readily than Sodium Iodide and hence is convenient to use.


Potassium iodide is produced industrially by treating Iodine with Potassium Hydroxide. It can also be prepared by the action of Potassium Bicarbonate on Hydriodic acid.


Potassium Iodide contains Iodine , an essential trace element required for overall development of the body and also for the effective functioning of the Thyroid gland to produce Thyroid hormones [ Thyroxine( T4 ), Triiodothyronine (T3)] that control the Body’s metabolic functions , the nerve and muscle functions. The deficiency of iodine leads to a disease known as Goiter that results into an enlargement in the size of the Thyroid gland.


Potassium iodide being an efficacious source of iodine plays a key role as a nutritional additive in the livestock feed , cattle feed for the treatment and control of iodine related deficiencies .


It is a safe additive for all animal species / categories if used up to the currently authorized maximum content of total iodine in the complete feed and as per the permissible tolerable limits.
