1. Consider the following electrochemical cell for measuring Hg2+:
SCE||Hg(NO3)2, Hg2Cl2|Pt
With the half reaction:
2Hg2+ + 2e-->Hg22+ E0 = 0.908 V
a) If, for a given concentration of Hg(NO3)2 and Hg2Cl2, the cell voltage reads 0.422 V, what would the cell voltage read if a Ag/AgCl reference electrode were used instead?
b) What would the cell voltage be if a standard hydrogen electrode were used?
