What kind of reaction is for Zn and CuS04?

So, here, on adding zinc to CuSO4 solution, zinc displaces copper from copper sulfate & forms zinc sulfate solution. This is indicated by color change from blue to colorless. CuSO4 solution has a blue color while ZnSO4 solution is colorless. Zn (s) + CuSO4 (aq) - > Cu (s) + ZnSO4 (aq).
