\(\mathrm{PbCl}_{2}\) is insoluble in cold water. Addition of \(\mathrm{HCl}\) increases its solubility due to
- A formation of soluble complex anions like \(\left[\mathrm{PbCl}_{3}\right]^{-}\)
- B oxidation of Pb(II) to PB(iV)
- C formation of \(\left[\mathrm{Pb}(\mathrm{H}_{2}\mathrm{O})_{6}\right]^{2}\)
- D formation of polymeric lead complexes
Answer & Solution
Correct Answer
(A) formation of soluble complex anions like \(\left[\mathrm{PbCl}_{3}\right]^{-}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{PbCl}_{2}\) react with HCl as follows \(\mathrm{PbCl}_{2}(s)+\mathrm{Cl}^{-} \stackrel{\text { Cold }}{\longrightarrow}\left[\mathrm{PbCl}_{3}\right]^{-}(a q)\)…
