  2. Name the type of reaction involved.
✓

Answer

When a strip of zinc metal is placed in copper sulphate solution, then zinc sulphate solution and copper are obtained.
  1. $\text{Zn(s)}\ \ +\ \ \text{CuSO}_4(\text{aq})\ \ \xrightarrow{\ \ \ \ \ \ \ \ \ \ \ \ \ }\ \ \text{ZnSO}_4(\text{aq})\ \ +\ \ \text{Cu(s)}\\ \ ^\text{Zinc}\ \ \ \ \ \ \ \ \ \ \ ^\text{Copper Sulphate}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ^\text{Zinc Sulphate}\ \ \ \ \ \ \ \ \ \ \ ^\text{Copper}$
  2. Displacement reaction.
