Some of the first complexes discovered by Werner in the 1890 s had the empirical formulas given below. Also given are the number of chloride ions per formula unit precipitated by the addition of $\mathrm{Ag}^{+}(a q) .$ Explain these observations. $$ \begin{array}{lc} \hline \begin{array}{l} \text { Empirical } \\ \text { formula } \end{array} & \begin{array}{l} \text { Number of Cl }^{-} \text {per formula } \\ \text { unit precipitated by } \mathbf{A g}^{+}(a q) \end{array} \\ \hline \mathrm{PtCl}_{2} \cdot 4 \mathrm{NH}_{3} & 2 \\ \mathrm{PtCl}_{2} \cdot 3 \mathrm{NH}_{3} & 1 \\ \mathrm{PtCl}_{2} \cdot 2 \mathrm{NH}_{3} & 0 \end{array} $$
