Which one of the following statements is correct?a)From a mixed precip...
Statement: From a mixed precipitate of AgCl and AgI, ammonia solution dissolves only AgCl.

Explanation:
When a mixed precipitate of AgCl and AgI is treated with ammonia solution, only AgCl dissolves while AgI remains insoluble.

Reasoning:
When AgCl is treated with ammonia solution, it forms a soluble complex ion called diammine silver(I) ion ([Ag(NH3)2]+). This complex ion is formed due to the reaction between AgCl and ammonia:

AgCl + 2NH3 → [Ag(NH3)2]+ + Cl-

On the other hand, AgI does not react with ammonia to form a soluble complex ion. Hence, when the mixed precipitate of AgCl and AgI is treated with ammonia solution, only AgCl dissolves and AgI remains as a solid.

Conclusion:
Therefore, the correct statement is option 'A': From a mixed precipitate of AgCl and AgI, ammonia solution dissolves only AgCl.
