For the cell diagram Cd(s)|CdSO 4 (aq)|Hg 2 SO 4 |Hg(l) What reaction occurs at the cathode?

The cathode is where reduction occurs in an electrochemical cell. The correct choice, D, describes the reduction of mercury sulfate to liquid mercury and sulfate ions, which is consistent with the behavior of a cathode in an electrochemical cell involving mercury.
