In chemistry, the iodine value (IV; also iodine adsorption 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. In fatty acids, unsaturation … See more The determination of iodine value is a particular example of iodometry. A solution of iodine I2 is yellow/brown in color. When this is added to a solution to be tested, however, any chemical group (usually in this test −C=C− … See more Hübl method The basic principle of iodine value was originally introduced in 1884 by A.
