Iodine

Symbol: I

Atomic Number: 53

Atomic Weight: 126.904

Iodine (atomic number 53, symbol I) is a chemical element with low toxicity, which dissolves easily in chloroform, hexane, and other organic solvents due to its lack of polarity. The color of iodine solutions depends on the solvent and its polarity. Solutions are violet in color in hexane and other non-polar solvents and dark crimson in moderately polar ones. Solutions are brown or orange in strongly polar solvents, for example, ethanol and acetone. When iodine is dissolved in carbon disulphide, carbon tetrachloride, or chloroform, it yields purple-colored solutions. Iodine is slightly soluble in water and gives a yellow solution.
