Potassium iodide is a precursor to silver iodide (AgI) an important chemical in photography. KI is a component in some disinfectants and hair treatment chemicals. KI is also used as a fluorescence quenching agent in biomedical research.
The major uses of KI include use as a nutritional supplement in animal feeds and also the human diet. For the latter, it is the most common additive used to "iodize" table salt (a public health measure to prevent iodine deficiency in populations which get little seafood). The oxidation of iodide causes slow loss of iodine content from iodized salts that are exposed to excess air. Potassium iodide is also used in several pharmaceutical preparations and for protection against nuclear radiation.
Potassium Iodide USP
KI -- 166.00
Potassium iodide -- [CAS 7681-11-0]
Potassium Iodide contains not less than 99.0 percent and not more than 101.5 percent of KI, calculated on the dried basis.
Identification— A solution of it meets the requirements of the tests for Potassium and for Iodide.
Alkalinity— Dissolve 1.0 g in 10 mL of water, and add 0.1 mL of 0.1 N sulfuric acid and 1 drop of phenolphthalein TS: no color is produced.
Loss on drying— Dry it at 105C for 4 hours: it loses not more than 1.0% of its weight.
Iodate— Dissolve 1.1 g in sufficient ammonia- and carbon dioxide-free water to obtain 10 mL of solution, and transfer to a color-comparison tube. Add 1 mL of starch TS and 0.25 mL of 1.0 N sulfuric acid, mix, and compare the color with that of a control containing, in a similar volume, 100 mg of Potassium Iodide, 1 mL of standard iodate solution [prepare by diluting 1 mL of potassium iodate solution (1 in 2500) with water to 100 mL], 1 mL of starch TS, and 0.25 mL of 1.0 N sulfuric acid. Any color produced in the solution of the test specimen does not exceed that in the control: not more than 4 µg per g is found.
Limit of nitrate, nitrite, and ammonia— To a solution of 1 g in 5 mL of water contained in a test tube of about 40-mL capacity add 5 mL of 1 N sodium hydroxide and about 200 mg of aluminum wire. Insert a pledget of purified cotton in the upper portion of the test tube, and place a piece of moistened red litmus paper over the mouth of the tube. Heat the test tube and its contents in a steam bath for 15 minutes: no blue coloration of the paper is discernible.
Thiosulfate and barium— Dissolve 0.5 g in 10 mL of ammonia- and carbon dioxide-free water, and add 2 drops of 2 N sulfuric acid: no turbidity develops within 1 minute.
Heavy metals— Dissolve 2.0 g in 25 mL of water: the limit is 0.001%.

They who love thee on this earth, keep calling on thee and chanting thy beads
Lest thou forgetest.
They assign the credit of their hard work to your blessings
They keep you amused.
They come to thy temple with baskets of fruits, as if you were a glutton
They deny the same to their children.
They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.
They bring gold and diamonds. They come with beating of drums
They love to advertise their offerings.
They offer you a small bribe as advance for booty, called lottery
They love to dream.
I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you.
