Electroplating waste solution consisting of H2SO4 and 0.5 M CuSO4 at room temperature has seriously attacked Fe-Cr alloy drains and holding tanks. (a) What are the relevant (list all) anode and cathode reactions? (b) Calculate the half-cell potential of each electrode reaction (for all reactions). pH = 1.5. The activity coefficient of Cu2+ = 0.21 M-1.
