Potassium iodide has the chemical formula K I. [8] Commercially it is made by mixing potassium hydroxide with iodine. [9] [10] Potassium iodide has been used medically since at least 1820. [11] It is on the World Health Organization's List of Essential Medicines. [12] Potassium iodide is available as a generic medication and over the counter. [13]
Formula: I 3 K: Molar mass: 419.812: ... Potassium iodide does not provide immediate protection but can be a component of a general strategy in a radiation emergency.
An extreme example is saturated solution of potassium iodide (SSKI) which attains 100 "%" m/v potassium iodide mass concentration (1 gram KI per 1 mL solution) only because the solubility of the dense salt KI is extremely high in water, and the resulting solution is very dense (1.72 times as dense as water).
It can also be prepared by adding iodine to a hot, concentrated solution of potassium hydroxide: [1] 3 I 2 + 6 KOH → KIO 3 + 5 KI + 3 H 2 O. Or by fusing potassium iodide with potassium chlorate, bromate or perchlorate, the melt is extracted with water and potassium iodate is isolated from the solution by crystallization: [2] KI + KClO 3 → ...
In chemistry, the iodine value (IV; also iodine absorption value, iodine number or iodine index) is the mass of iodine in grams that is consumed by 100 grams of a chemical substance. Iodine numbers are often used to determine the degree of unsaturation in fats, oils and waxes.
