Sagot :
PbCl2 is more soluble in acid as compared to other salts of lead.
Four salts of lead are more soluble in acid solution than water.
[tex]PbS[/tex] ⇒ [tex]Pb^{2+} + S^{2-}[/tex]
[tex]2H^{+} + S^{2-}[/tex] ⇒ [tex]H_{2}S[/tex]
As [tex]S^{2-}[/tex] ions are removed from the solution by the formation of [tex]H_{2} s[/tex], the solubility of [tex]PbS[/tex] increases in acid solution.
[tex]PbCo_{3}[/tex] ⇒ [tex]Pb^{2+} + Co_{3} ^{2-}[/tex]
[tex]2H^{2+} + Co_{3} ^{2-}[/tex] ⇒ [tex]H_{2} Co_{3}[/tex]
As [tex]Co_{3}[/tex] ions are removed from the solution by the formation of [tex]H_{2} Co_{3}[/tex], the solubility of [tex]PbCo_{3}[/tex] increases in acid solution.
[tex]PbCl_{2}[/tex] ⇒ [tex]Pb^{2+} + 2Cl^{-}[/tex]
[tex]2H^{+} + 2Cl^{-}[/tex] ⇒[tex]2HCl[/tex]
As [tex]Cl^{-}[/tex] ions are removed from the solution by the formation of HCl, the solubility of [tex]PbCl_{2}[/tex] increases in acid solution.
[tex]PbI_{2}[/tex] ⇒ [tex]Pb^{2+} + 2I^{-}[/tex]
[tex]2H^{+} + 2I^{-}[/tex] ⇒ [tex]2HI[/tex]
As [tex]I^{-}[/tex] are removed from the solution by the formation of [tex]HI[/tex], the solubility of [tex]PbI_{2}[/tex] increases in acid solution.
Thus from above we concluded that all the given salt of lead is more soluble in acid solution than in water.
