Answer 1

When one mole of [Co(NH₃)₅Cl]Cl₂ is treated with excess of AgNO₃ solution, two mole(s) of AgCl_(s) is formed.

Explanation:

The complex [Co(NH₃)₅Cl]Cl₂ ionizes to give a complex cation and two chloride ions.

$$[\mathrm{Co}(\mathrm{NH}{\phantom{A}}_3){\phantom{A}}_5\mathrm{Cl}]\mathrm{Cl}{\phantom{A}}_2⟶[\mathrm{Co}(\mathrm{NH}{\phantom{A}}_3){\phantom{A}}_5\mathrm{Cl}]{\phantom{A}}^{2+}+2\mathrm{Cl}{\phantom{A}}^{-}$$

lonizable chloride ions react with AgNO₃ to give 2 moles of AgCl.

$$2\mathrm{Cl}{\phantom{A}}^{-}+2\mathrm{AgNO}{\phantom{A}}_3⟶2\mathrm{AgCl}{\phantom{A}}_{(\mathrm{s})}$$
