Question

If a diluted solution of h2so4 is electrolyzed with copper electrodes, the most likely electrode reactions are: 2H + + 2e = H2 at the cathode and 2Cu (s) + H2O = Cu2O (s) + 2H + + 2e at the anode. If we observe the formation of 27.4 cc of wet hydrogen (751 barometric torr, 23.3 C) in the cathode, what change of peao will be simultaneously in the anode?

what weight change will there be simultaneously in the anode?*

Answer: 17,4 mg
