Vedclass · Answer

(A) The reaction of halide ions with $AgNO_3$ in the presence of $HNO_3$ produces silver halides: $Ag^{+} + Cl^{-} \rightarrow AgCl$ (White precipitate,readily soluble in $NH_4OH$). $Ag^{+} + Br^{-} \rightarrow AgBr$ (Pale yellow precipitate,soluble with difficulty in $NH_4OH$). $Ag^{+} + I^{-} \rightarrow AgI$ (Yellow precipitate,insoluble in $NH_4OH$). Since the precipitate is pale yellow and soluble with difficulty in $NH_4OH$,it indicates the presence of $Br^{-}$ ions.

During the detection of an acidic radical present in a salt,a student obtains a pale yellow precipitate that is soluble with difficulty in $NH_4OH$ solution when the sodium carbonate extract is first acidified with dil. $HNO_3$ and then $AgNO_3$ solution is added. This indicates the presence of:
