Consider the following equilibrium
$$
\mathrm{AgCl} \downarrow+2 \mathrm{NH}_3 \rightleftharpoons\left[\mathrm{Ag}\left(\mathrm{NH}_3 2_2\right]^{+}+\mathrm{Cl}^{-}\right.
$$
White precipitate of $\mathrm{AgCl}$ appears on adding which of the following?

The correct answer is:
aqueous $\mathrm{HNO}_3$
aqueous $\mathrm{HNO}_3$
$2 \mathrm{HNO}_3(\mathrm{aq})+\left[\mathrm{Ag}\left(\mathrm{NH}_3\right)_2\right]^{+}+\mathrm{Cl}^{-}$
$$
\longrightarrow \mathrm{AgCl}(\mathrm{s}) \downarrow+2 \mathrm{NH}_4+2 \mathrm{NO}_3^{-}
$$
When nitric acid is added to amine solution, solution is made acidic and the complex ion dissociates and liberate silver ion to recombine with chloride ion. This is the conformatory test for silver in group 1 .
