A) \[AgN{{O}_{3}}\] solution after boiling with KOH
B) Ammonical cuprous chloride
C) Fehling solution
D) \[AgN{{O}_{3}}\]
Correct Answer: D
Solution :
A pure sample of \[CHC{{l}_{3}}\] produces no. ppt. of \[AgCl\] with \[AgN{{O}_{3}}\] because it does not contain \[C{{l}^{-}}\](chloride) ions. An impure sample. (Which has been oxidised by air) forms a white ppt. of \[AgCl\] with because \[A{{g}^{+}}\] from \[AgN{{O}_{3}}\]combine with the \[C{{l}^{-}}\] ions of \[HCl\] formed by oxidation of \[CHC{{l}_{3}}\].
