A cell is set up with a nickel electrode and a nickel sulfate solution in the left hand compartment and a cobalt electrode and a cobalt nitrate solution in the right hand compartment.
a) If both solutions are 1.0 M, what will the cell potential be and which electrode will be the cathode?
b) If the concentration of cobalt nitrate stays at 1.0 M, to what value would you have to lower the nickel ion concentration to cause the cell to run in the opposite direction(compared to part a)?
