Audited Supplier CAS No. 7681-11-0 Potassium Iodide with High Purity
Potassium iodide
1. Properties:
colorless monoclinic crystal or white crystalline powder, soluble in water, dilute acid and ethylene diamine, ethanolamine and potassium iodide solution; Slightly soluble in liquid sulphur dioxide and ammonia; Insoluble in alcohol and ammonia. In alkaline medium, potassium iodate, hypochlorous acid, etc can be chlorine gas stronger antioxidant for potassium periodate oxidation.

2. Usage:
1)Potassium iodide, also called KI is a salt of stable (not radioactive) iodine. The compound is required by the body to make thyroid hormones.
2)The major uses of potassium iodide include nutritional supplement in animal feeds. It is also used medicinally in tablets, and also fins application in hair dyes.
3)Potassium Iodide is sometimes added in small quantities to table salt for idolization. This crystalline salt is also used as a fluorescence quenching agent in biomedical research because of collisional quenching by its iodide ion.
4. Used as an analytical reagent, such as preparing an iodine standard solution as an auxiliary reagent. Also used as a photosensitive emulsifier, feed additive. Used in the pharmaceutical industry.
5. Potassium iodide is a co-solvent for iodine and certain poorly soluble metal iodides.
6. Potassium iodide has two main applications in surface treatment: one is for chemical analysis, the medium reduction of iodide ion and some oxidative ion reaction are used to generate elemental iodine, and then the iodine is determined to calculate The concentration of the analyte; the second is for the complexation of certain metal ions, and its typical use is as a complexing agent for cuprous and silver in electroplated copper-silver alloys.
7. The so-called iodized edible salt that we often eat is to add potassium iodide or potassium iodate (in proportion to 20,000) to ordinary salt (pure sodium chloride).
8. Potassium iodide has some special uses in the field of dermatology. Its mechanism of action is partly due to enhanced dissolution and digestion of necrotic tissue. Potassium iodide also has antifungal activity. It is used clinically to treat sporotrichosis, pigmented blastomycosis, persistent nodular erythema, and nodular vasculitis. When using potassium iodide, you should also pay attention to its side effects. It can cause pustules, blisters, erythema, eczema, urticaria, etc. It can also aggravate acne, and of course can cause digestive tract reactions and mucosal symptoms.
9. It is used in medicine to prevent and treat endemic goiter and promote the absorption and sputum of vitreous opacity of the eye. It can also be used as analytical reagents, chromatography, and point pain analysis.
10. Potassium iodide can also measure the ozone concentration, and replace the iodine to make the starch blue. The reaction is as follows:
O3+2KI+H2O=2KOH+O2+I2 [2]
