Salt that dissolves in aqueous ammonia solution is-a)(HgCl2)b)(PbCl2)...
Copper(II) ion reacts with stoichiometric quantities of aqueous ammonia to precipitate light blue (Cu(OH)2). Some essential salts may also form. The precipitate does not dissolve in excess sodium hydroxide unless the NaOH solution is very concentrated.

Salt that dissolves in aqueous ammonia solution is-a)(HgCl2)b)(PbCl2)...
Explanation:
Salt Dissolving in Aqueous Ammonia Solution:
- When a salt dissolves in aqueous ammonia solution, it undergoes a reaction with ammonia to form a complex ion.
Identification of the Salt:
- In this case, the salt that dissolves in aqueous ammonia solution is Cu(OH)2.
Explanation of the Reaction:
- When Cu(OH)2 reacts with ammonia, it forms a complex ion [Cu(NH3)4]2+.
Reasoning:
- The other options (HgCl2, PbCl2, Al(OH)3) do not form complex ions in aqueous ammonia solution and therefore do not dissolve.
Conclusion:
- The correct answer is option (C) Cu(OH)2 as it forms a complex ion in aqueous ammonia solution and dissolves.
