Potassium iodide is used to make organic compounds and chemical reagents. The so-called iodized table salt we often eat is to add potassium iodide or potassium iodate (at a rate of one in 20,000) to common table salt (pure sodium chloride).
has some special uses in dermatology, and its mechanism is partly due to enhanced dissolution and digestion of necrotic tissue. Potassium iodide also has antifungal activity and is used clinically to treat sporotrichosis, dysentery, persistent erythema nodosum, and vasculitis. When using potassium iodide, you should also pay attention to its side effects, which can cause pustules, blisters, erythema, eczema, urticaria and so on.

Potassium iodide is a drug for preventing and treating endemic goiter, which promotes the absorption and phlegm of vitreous opacity. Potassium iodide is the raw material for preparing iodide and dyes.
Potassium chloride is used as a co-solvent for photosensitive emulsifiers, food additives, iodine and some insoluble metal iodides. It can also be used as analytical reagent, chromatographic analysis and speckle analysis.
Potassium iodide is a stabilizer and auxiliary solvent. Feed grade potassium iodide can also be used as a supplement to iodine in feed processing. Potassium iodide can also measure ozone concentration, instead of iodine to make starch blue, the reaction is as follows: O3 + 2KI + H2O = 2KOH + O2 + I2
