JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Question Bank Self Evaluation Test - Equilibrium

  • question_answer
    Consider the following equilibrium \[AgCl\downarrow +2N{{H}_{3}}\rightleftharpoons {{\left[ Ag{{(N{{H}_{3}})}_{2}} \right]}^{+}}+C{{l}^{-}}\] White precipitate of \[AgCl\] appears on adding which of the following?

    A) \[N{{H}_{3}}\]                        

    B) aqueous \[NaCl\]

    C) aqueous\[HN{{O}_{3}}\]  

    D) aqueous \[N{{H}_{4}}Cl\]

    Correct Answer: C

    Solution :

    [c] \[2HN{{O}_{3}}\left( aq \right)+[Ag{{\left( N{{H}_{3}} \right)}_{2}}^{+}+C{{l}^{-}}\] \[\xrightarrow{{}}AgCl\left( s \right)\downarrow +2N{{H}_{4}}+2NO_{3}^{-}\] 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.
