Ÿ Anode is in the negative side (left side of the diagram)

▪ Anode → oxidation

oxidation half-reaction happens in the anode solution

▪ losing electrons → becoming more positive → anode dissolves away

Ÿ Cathode is in the positive side (right side of the diagram)

▪ Cathode → reduction

reduction half-reaction happens in the anode solution

▪ gaining electrons → becoming more negative → solids is deposited in the surface
