prepared directly by dissolving iodine in water because iodine is too volatile so it is almost impossible to avoid loss while the solution is being prepared. Therefore iodine is prepared in situ by mixing pure potassium iodate (KIO3 ) and potassium iodide (KI) in acidified medium. IO3- + 5I- + 6H+ → 3I2 + 3H2O The excess iodine that has not reacted with ascorbic acid in fruit juices (vitamin C) is then back titrated by standardized sodium thiosulphate solution. Iodine can be decolourized
