A metal nitrate solution reacts with dilute hydrochloric acid to give a white precipitate which is soluble in concentrated potassium chloride. White precipitate on passing of hydrogen sulphide gas is converted into black precipitate. The black precipitate on boiling with hydrogen peroxide (3%) is converted again to a white precipitate which is soluble in ammonium acetate. The cation of the metal nitrate is :
  • a)
    Pb2+
  • b)
    Ag+
  • c)
    Hg2+
  • d)
    Bi3+
Correct answer is option 'A'. Can you explain this answer?

Reaction with Dilute Hydrochloric Acid
The metal nitrate solution reacts with dilute hydrochloric acid to form a white precipitate. This indicates the formation of a chloride salt that is insoluble in water.
Nature of the White Precipitate
- The white precipitate formed is likely lead(II) chloride (PbCl2), which is known to be white and somewhat soluble in concentrated potassium chloride due to the common ion effect.
Reaction with Hydrogen Sulfide
- When hydrogen sulfide (H2S) gas is passed through the solution containing the white precipitate, a black precipitate is formed.
- This black precipitate corresponds to lead(II) sulfide (PbS), which is insoluble and known for its distinct black color.
Effect of Boiling with Hydrogen Peroxide
- Boiling the black precipitate (PbS) with 3% hydrogen peroxide converts it back to a white precipitate, which is lead(II) sulfate (PbSO4).
- Lead(II) sulfate is a white solid that can be dissolved in ammonium acetate, confirming the presence of lead ions.
Conclusion
- The entire reaction sequence strongly indicates that the cation of the metal nitrate is lead (Pb2+).
- The reactions and transformations observed align perfectly with the known chemistry of lead, confirming option 'A' as the correct answer.
In summary, the metal nitrate solution is identified as lead(II) nitrate due to its characteristic reactions with hydrochloric acid, hydrogen sulfide, and hydrogen peroxide.
