Group VII of the Periodic Table consists of the halogens. These elements show distinct trends in their physical and chemical properties.
(a) State the appearance (colour and state) of bromine at room temperature and pressure.
(b) A student adds aqueous chlorine to a test-tube containing potassium iodide solution. Describe the change in appearance of the solution and explain the reaction in terms of the reactivity of the halogens involved.
(c) Construct the word equation for the reaction described in part (b).
