Water produces H+H^+H+ and OH−OH^-OH− ions that can react
H+H^+H+ and OH−OH^-OH− ions
Compound ions AND H+H^+H+/OH−OH^-OH− from water
Less reactive ion is reduced
Ion oxidised more easily is oxidised
Less reactive
Solid copper deposits
Cu2+(aq)+2e−→Cu(s)Cu^{2+}(aq) + 2e^- \to Cu(s)Cu2+(aq)+2e−→Cu(s)
When no halide ions present
Oxygen gas and water
4OH−(aq)→2H2O(l)+O2(g)+4e−4OH^-(aq) \to 2H_2O(l) + O_2(g) + 4e^-4OH−(aq)→2H2O(l)+O2(g)+4e−
H+H^+H+ ions reduced instead
Halide ions (e.g., Cl−Cl^-Cl−)
