A cell is set up with copper and lead electrodes in contact with CuSO₄(aq) and Pb(NO₃)₂(aq), respectively, at 25°C. The standard reduction potentials are:

Pb²⁺ + 2e^– Pb E° = –0.13 V

Cu²⁺ + 2e^– Cu E° = +0.34 V

If sulfuric acid is added to the Pb(NO₃)₂ solution, forming a precipitate of PbSO₄, the cell potential:

◦ increases
◦ decreases
◦ is unchanged
◦ It would change, but the direction of change cannot be determined.
◦ None of these are correct.
