Consider the electrolysis reactions cathode anode H₂O(1) whose standard reduction potentials can be found in this table. Calculate the voltage needed to drive the net reaction if the current is negligible. Ecell = Cu²+ (aq, 0.253 M) + 2e = Cu(s) 1 O₂(g, 1 bar) + 2 H+ (aq, 0.202 M) + 2 e¯ 2 -0.858 The cell has a resistance of 57.0 2 and a current of 4.73 mA when the cathode overpotential is 0.232 V and overpotential is 0.054 V. Calculate the voltage needed to overcome these effects and drive the net reaction.
