Problem: You have a concentration cell in which the cathode has a silver electrode with 0.10 M Ag+. The anode also has a silver electrode with Ag +(aq), 0.050 M S 2O3 2-, and 1.0 X 10 -3 M Ag(S2O3)2 3-. You read the voltage to be 0.76 V.a. Calculate the concentration of Ag + at the anode.

FREE Expert Solution

The Nernst Equation:

Ecell=E°cell-(0.05916 Vn)logQ

Ecell = cell potential under non-standard conditions
cell = standard cell potential
n = number of e- transferred
Q= reaction quotient = [products]/[reactants]
