    Whether or not there is a reaction is determined by the relative positions of the cations or metals in the activity series, as shown in the source below.

    1.Mg+CuCl2→Cu+MgCl2

    2.Mg+ZnCl2→Zn+MgCl2

    3.Mg+FeCl2→Fe+ MgCl2

    4.Cu+MgCl2→ no reaction

    5.Cu+ZnCl2→ no reaction

    6.Cu+FeCl2→ no reaction

    7.Zn+MgCl2→ no reaction

    8.Zn+CuCl2→Cu+ZnCl2

    9.Zn+FeCl2→Fe+ZnCl2

    10.Fe+MgCl2→ no reaction

    11.Fe+CuCl2→Cu+FeCl2

    12.Fe+ZnCl2→ no reaction
