WebExample Find the cell potential of a galvanic cell based on the following reduction half-reactions where [Ni 2+] = 0.030 M and [Pb 2+] = 0.300 M. Ni 2+ + 2 e- → Ni, E 0 = -0.25 V Pb 2+ + 2 e- → Pb, E 0 = -0.13 V First, find the electromotive force for the standard cell, which assumes concentrations of 1 M. WebIn the formula E (cell)= E (cathode) - E (anode) we have a positive value for the E (cathode) and a negative value for E (anode) since their REDUCTION potentials are positive and negative, respectively. lutheran women\u0027s missionary league canada https://mbsells.com
