    When dilute aqueous solution of\[AgN{{O}_{3}}\] (excess) is added to \[KI\] solution, positively charged sol of \[Agl\] in formed due to adsorption of

    A) \[NO_{3}^{-}\]                                 

    B) \[O_{2}^{-}\]

    C) \[A{{g}^{+}}\]                                   

    D) \[{{K}^{+}}\]

    Correct Answer: C

    Solution :

                    When aqueous solution of \[AgN{{O}_{3}}\] is added to \[Kl\] solution, positively charged sol of \[Agl\] is obtained due to adsorption of \[A{{g}^{+}}\] ions on \[Agl\] molecules. \[AgN{{O}_{3}}+Kl\xrightarrow{{}}\underset{Positively\,\,ch\arg ed\,sol}{\mathop{\underset{\begin{smallmatrix}  \downarrow A{{g}^{+}} \\  [Ag]A{{g}^{+}} \end{smallmatrix}}{\mathop{Agl+}}\,KN{{O}_{3}}}}\,\]
