A Zn wire and Ag/AgCl reference electrode saturated with KCl (E = 0.197 V) are placed into a solution of ZnSO . 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 -1.079 V. The standard reduction potential of the Zn²+/Zn half-reaction is -0.762 V. M [Zn*] =
