State what you would see on;

(i) bubbling SO\(_2\) into acidified KMnO\(_4\) solution

(ii) mixing zinc dust with CuSO\(_4\) solution

(iii) adding concentrated HNO\(_3\) to freshly prepared FeSO\(_4\) solution.

(b) List two substances in case which, if added to dilute H\(_2\)SO\(_4\), would give you

(i) H\(_{2(g)}\)

(ii) ZnSO\(_{4(aq)}\)

(c)  The diagram labeled I to IV ABOVE illustrate different laboratory set-ups used in the separation of mixtures.

(i) Name the separation technique illustrated by each diagram

(ii) Which of the set-ups is used for concentrating dilute salt solutions, for the purpose of crystallization?

(iii) Which of the set-ups is used in obtaining clear water from muddy water?

(iv) Mention the set-up you would use to separate a polar solvent from a non-polar solvent

(v) State the modification you would make to the set-up labelled IV in order to use it for separating a mixture of NaCl and NH\(_4\)CI
