Question

Describe an experiment which shows that chlorine is more reactive than iodine. Include an equation in your answer.​

Answer 1

Create a solution of chloride water and add a colouless solution of potassium iodide... The mixture will turn red-brown because iodine has been displaced proving that it is less reactive than chlorine

Cl2 (aq) + 2KI (aq) --> 2KCl (aq) + I2 (aq)
