The iodine test is used to test for the presence of starch i.e.carbohydrates . starch turns into an intense blue black colour upon addition of aqueous solution of the formation of an intermolecular charge transfer complex.

iodine solution is used to detect the presence of the carbohydrates in the solution. Generally, the test is performed to detect the presence of starch which is a carbohydrate. When there is presence of starch in the sample solution, the colour of the solution turns bluish black after the addition of the iodine solution.
