PASSAGE-2
An aqueous solution of a mixture of two inorganic salts, when treated with dilute HCl, gave a precipitate (P) and a filtrate (Q).
The precipitate P was found to dissolve in hot water. The filtrate (Q) remained unchanged, when treated with H2S in a dilute mineral acid medium. However, it gave a precipitate (R) with H2S in an ammoniacal medium. The precipitate R gave a coloured solution (S), when treated with H2O2 in an aqueous NaOH medium. (JEE Adv. 2013-II)
Q. The precipitate P contains  
  • a)
    Pb2+
  • b)
    Hg22+
  • c)
    Ag+
  • d)
    Hg2+
Correct answer is option 'A'. Can you explain this answer?

Answer:

Identification of the Inorganic Salts

Precipitate P:

- Dissolves in hot water, indicating that it is a salt of a metal with a low solubility product.
- Does not react with H2S in a mineral acid medium, indicating that it does not contain a sulphide ion.
- Therefore, precipitate P contains a metal ion that can form a low solubility product with Cl- ion.

Filtrate Q:

- Remains unchanged when treated with H2S in a mineral acid medium, indicating that it does not contain a sulphide ion.
- Forms a precipitate R with H2S in an ammoniacal medium, indicating that it contains a metal ion that can form a complex with NH3 and has a low solubility product with H2S in an ammoniacal medium.
- Therefore, filtrate Q contains a metal ion that can form a complex with NH3 and has a low solubility product with H2S in an ammoniacal medium.

Coloured solution S:

- Obtained by treating precipitate R with H2O2 in an aqueous NaOH medium.
- Indicates the presence of a metal ion that can form a coloured complex with H2O2 in an alkaline medium.
- Therefore, coloured solution S confirms the presence of a metal ion in precipitate R.

Conclusion:

- Precipitate P contains a metal ion that can form a low solubility product with Cl- ion, which is Pb2+ ion.
- Filtrate Q contains a metal ion that can form a complex with NH3 and has a low solubility product with H2S in an ammoniacal medium, which is Cu2+ ion.
- Coloured solution S confirms the presence of a metal ion in precipitate R, which is Cu2+ ion.
