Zinc displacing copper. Image 1 of 2. Zinc (Zn) metal being placed in a solution (blue) of copper (II) sulphate (CuSO4). Solid copper (Cu) will be formed as the copper is replaced in the solution by zinc. This is a displacement or substitution reaction. The zinc is more reactive than copper, and can be placed above it in a reactivity series. For the finished reaction, see image A500/304.
