A) \[C{{l}^{-}}\]
B) \[B{{r}^{-}}\]
C) \[{{I}^{-}}\]
D) \[NO_{3}^{-}\]
Correct Answer: A
Solution :
When \[C{{l}^{-}}\], \[B{{r}^{-}}\] and \[{{F}^{-}}\] are treated with \[AgN{{O}_{3}}\] solution in presence of dilute \[HN{{O}_{3}}\], corresponding silver halide is obtained which is soluble in \[N{{H}_{4}}OH,\] NaCN, and \[N{{a}_{2}}{{S}_{2}}{{O}_{3}}\]. \[AgN{{O}_{3}}\ +\ NaCl\ \xrightarrow{{}}\ \underset{\text{white}}{\mathop{AgCl}}\,\downarrow \ +\ NaN{{O}_{3}}\] \[AgCl\ +\ dil.2N{{H}_{4}}OH\ \xrightarrow{{}}\underset{\text{complex}}{\mathop{\ \left[ Ag{{(N{{H}_{3}})}_{2}} \right]\,Cl\,}}\,+2{{H}_{2}}O\]You need to login to perform this action.
