Verified Solution

Answer & Solution

Correct Answer

(B) \(HgI_4^{2-}, I^-_3\)

Step-by-step Solution

Detailed explanation

\(\mathrm{HgCl}_{2}+2 \mathrm{I}^{-} \longrightarrow \mathrm{HgI}_{2}+2 \mathrm{Cl}^{-} \)\(\stackrel{+2I^-}{\longrightarrow}\left[\mathrm{HgI}_{4}\right]^{-2}\) Soluble complex
