\left ( i \right )\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right] \mathrm{Cl}+\mathrm{AgNO}_3 \rightarrow\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}+\mathrm{AgCl}

(ii) \left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_2+\mathrm{AgNO}_3 \rightarrow\left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{+2}+2 \mathrm{AgCl}

(iii) \left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]+\mathrm{AgNO}_3 \rightarrow$ no $\mathrm{AgCl}$ mole are $\mathrm{ppt}

(iv) \left[\mathrm{Pd}\left(\mathrm{NH}_3\right)_4\right] \mathrm{Cl}_2+\mathrm{AgNO}_3 \rightarrow\left[\mathrm{Pd}\left(\mathrm{NH}_3\right)_4\right]^{+2}+2 \mathrm{AgCl}

Total 5 mole \mathrm{AgCl} are formed.
