Water produces $H^+$ and $OH^-$ ions

$H^+$ and $OH^-$

The less reactive ion

The ion that can be oxidised most easily

$Cu^{2+}$ and $H^+$

Copper is less reactive than hydrogen

Solid copper deposits

$SO_4^{2-}$ and $OH^-$

$OH^-$ ions are oxidised

Oxygen gas and water

Halide ions

$H^+$ ions are reduced instead
