Answer to Question #71801 in General Chemistry for whitney

Question

A Zn wire and Ag/AgCl reference electrode (E° = 0.197 V) are placed into a solution of ZnSO4. 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 -1.061 V. The standard reduction potential of the Zn2+ /Zn half-reaction is –0.762 V.

[Zn2+]= ? M
