Water dissociates into H+H^+H+ and OH−OH^-OH− ions
H+H^+H+ and OH−OH^-OH− ions
Less reactive ion
Ion that can be oxidised more easily
Cu2+Cu^{2+}Cu2+ ions
Cu is less reactive than hydrogen
Solid copper
OH−OH^-OH− ions
OH−OH^-OH− more easily oxidised (no halides present)
Oxygen gas and water
H+H^+H+ ions from water instead
Halide ions
Cu2++2e−→CuCu^{2+} + 2e^- \rightarrow CuCu2++2e−→Cu
