A Zn wire and Ag/AgCl reference electrode saturated with KCI (E = 0.197 V) are placed into a solution of ZnSO₂. The Zn
wire is attached to the positive terminal and the Ag/AgCl electrode is attached to the negative terminal of the potentiometer.
Calculate the [Zn²+] in the solution if the cell potential, Ecell, is -1.088 V. The standard reduction potential of the Zn² Zn
half-reaction is -0.762 V.
[Zn²+ =
M
