Question

A voltaic cell is set up at standard conditions with a gold electrode in contact with Zn(NO3)2 (aq) and a lead electrode in contact with Pb(NO3)2 (aq) at 25°C.

Which of the following statements are TRUE about the reaction?  after some sodium sulfate solution is added to the PbSO4 solution, forming a precipitate

I. If sulfate solution is added to the lead half-cell and a precipitate forms then the cell potential will decrease.

II. The zinc electrode is increasing in mass.

III. This electrochemical cell will result in the production of Pb2+ ions.
