Vedclass · Answer

(B) $HgCl_2$ is a covalent compound that is sparingly soluble in water. When chloride ions $(Cl^-)$ are added to the solution,$HgCl_2$ reacts with them to form a soluble complex ion,$[HgCl_4]^{2-}$. The reaction is: $HgCl_2(s) + 2Cl^-(aq) \rightarrow [HgCl_4]^{2-}(aq)$. This complex formation increases the solubility of $HgCl_2$ in the presence of excess chloride ions.

$HgCl_2$ is a covalent compound,sparingly soluble in water. The solubility increases by the addition of chloride ions due to:
