Chemistry - Salt Analysis Question with Solution | TestHub

Concept:

Solubility products of chlorides, reaction of ${\mathrm{Hg}}_2{\mathrm{Cl}}_2$ with ammonia.

Solution:

(A) is the basis for separating ${\mathrm{Pb}}^{2+}$.

(B)${\mathrm{Hg}}_2{\mathrm{Cl}}_2+2{\mathrm{NH}}_3\to \mathrm{Hg}\left({\mathrm{NH}}_2\right)\mathrm{Cl}+\mathrm{Hg}+{\mathrm{NH}}_4\mathrm{Cl}$.

(C)${\left[\mathrm{Ag}{\left({\mathrm{NH}}_3\right)}_2\right]}^{+}$is linear.

(D) is false; conc. HCl forms soluble chloro-complexes like ${\left[{\mathrm{AgCl}}_2\right]}^{-}$.
