(a)(i) Give two uses of chlorine.

(ii) State the action of chlorine on moist blue litmus paper

(b) Draw a labelled diagram for the laboratory preparation of a dry sample of chlorine

(c) State the type of reaction involved between chlorine and (i) aqueous iron (II) chloride;

(ii) propane. Write an equation for each reaction and name the product formed in (c)(ii).

(d) Consider the reactions the following equations: Cl\(_{2(g)}\) + 2Br\(^-_{(aq)}\) \(\to\) 2Cl\(^-_{(aq)}\) + Br\(_{2(g)}\)

F\(_{2(g)}\) + 2Cl\(^-_{(aq)}\) ---> 2F\(^-_{(aq)}\) + Cl\(_{2(g)}\)

From the equations, arrange bromine, chlorine and fluorine in increasing order of oxidizing ability. Give the reason for your answer.
