Predicting the Products of Electrolysis Downs cell
2 • Electrolysis of water – Pure water is hard to electrolyze (low conductivity), so a small amount of a nonreactive salt (NaNO3) is added (can be neglected) →H2O is reduced at the hode: 2H2O(l) + 2e→H 2(g) + 2OHEo = V (at pH = 7) → E = V →H2O is oxidized at the anode: 2H2O(l) →O2(g) + 4H+ + 4eEo = + V (at pH = 7) → E= + V 4H2O(l) + 4e+ 2H
