This video demonstrates the rate of hydrolysis of the chlorobutane (left), bromobutane (middle) and iodobutane (right). The rate of hydrolysis is observed by the addition of silver ions which react with the halide ions to form a precipitate of the silver halide which can be observed as a white. cream and yellowy precipitate respectively.
