1. Calculate the real electrode potential and write down the diagram of the GE with a standard hydrogen electrode
3) a lead plate is lowered into a solution of 0.004 mol/l lead nitrate E0Pb2 /Pb0 = -0.126 volts
4) a chromium plate is lowered into a solution of 0.006 mol/l chromium sulfate E0Cr3 /Cr0 = -0.740 volts.
