Chemistry - Coordination Chemistry Question with Solution | TestHub

The number of ions will be precipitated only which are out of coordination sphere in given complexes.

$\left[\mathrm{Cr}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]{\mathrm{Cl}}_3\left(\mathrm{aq}\right)\rightleftarrows {\left[\mathrm{Cr}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{3+}\left(\mathrm{aq}\right)+\text{\hspace{0.17em}3}{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)$
$3{\mathrm{Ag}}^{+}+3{\mathrm{Cl}}^{-}\to 3\mathrm{AgCl}\downarrow \left(\mathrm{White}\right)$

More Equivalents of $\mathrm{A}\mathrm{g}\mathrm{N}{\mathrm{O}}_3$ aqueous solution will be consumed by more $\mathrm{C}{\mathrm{l}}^{-}$ ions given by the complex

$\mathrm{C}{\mathrm{l}}^{-}\left(\mathrm{a}\mathrm{q}\right)+\mathrm{A}\mathrm{g}\mathrm{N}{\mathrm{O}}_3\to \mathrm{A}\mathrm{g}\mathrm{C}\mathrm{l}\downarrow +\mathrm{N}{\mathrm{O}}_3^{-}\left(\mathrm{a}\mathrm{q}\right)$
