(a (i) Explain why water is referred to as a universal solvent.

(ii) Give one chemical test for water. H\(_2\)SO\(_4\)

(b) A current of 1.25A was passed through an electrolytic cell containing dil.  for 40 minutes.

(i) Write (ii) Calculate the volume of gas produced at the anode at s.t.p. (1F = 96,500 C, Molar Volume of gas at s.t.p. = 22.4 dm\(^3\) mol\(^{-3}\) ]

(C) Consider the reaction represented by the following equation: Au\(_{(s)}\) + Cl\(_{2(g)}\) \(\to\)  AuCl\(_{3(s)}\)

(I) Balance the equation

(ii) If 1.2509 of Au and 1.744g of Cl\(_2\) were mixed

I. determine which of the reactants is in excess II. calculate the excess amount [Au = 197.0, CI = 35.5]
