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
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
Suppose the galvanic cell sketched below is powered by the following reaction
Mg(s)+SnSO4(aq) → MgSO4(aq) + Sn(s)
Write a balanced equation for the half-reaction that happens at the cathode of this cell.
