WebA voltaic cell is constructed that is based on the following reaction: Sn^2+(aq)+Pb(s) = Sn(s)+ Pb^2+(aq) a) If the concentration of Sn2+ in the cathode compartment is 1.30 M and the cell generates an EMF of 0.22 V, what is the concentration of Pb2+ in t WebSo that would be positive .54 volts, so positive .54 plus 1.66, plus positive 1.66 volts. So the standard potential for the cell, so E zero cell is equal to .54 plus 1.66 which is equal to 2.20 volts. All right, now that we've found the standard cell potential, we can calculate the equilibrium constant.
