    (a)Using the information below, explain why copper(I) sulphate does not exist in aqueous solution.

    Cu2+(aq) + e- = Cu+(aq) E=+0.15V
    Cu+(aq) +e- = Cu(s) E=+0.52V

    (b) Explain why, in the presence of iodide ions, copper(I) ions can form and do not undergo disproportionation.

    Thanks in advance
