Which of the following compounds is sparingly soluble in ammonia

Options

A. Agl
B. AgBr
C. AgCl
D. `CuCl_(2)`

Answer

A

Explanation

`NH_(3)` is a polar solvent so ionic compounds like AgCl , AgBr and `CuCl_(2)` are soluble in aqueous solution of ammonia. Ammonia also forms complexes with `Ag^(+)` and `Cu^(2+)` ions.
But the covalent character in AgI is more than that in other compounds. So AgI is sparingly soluble in ammonia solution.
