    Complexes \[\left[ Co{{\left( N{{H}_{3}} \right)}_{5}}S{{O}_{4}} \right]Br\] and \[\left[ Co{{\left( N{{H}_{3}} \right)}_{5}}Br \right]S{{O}_{4}}\] can be distinguished by

    A) conductance measurement

    B) using \[BaC{{l}_{2}}\]

    C) using \[AgN{{O}_{3}}\]

    D) Both [b] and [c]

    Correct Answer: D

    Solution :

    [d] \[\left[ Co{{\left( N{{H}_{3}} \right)}_{5}}Br \right]S{{O}_{4}}\] gives white precipitate of \[BaS{{O}_{4}}\] with \[BaC{{l}_{2}}(aq)\] whereas\[\left[ Co{{\left( N{{H}_{3}} \right)}_{5}}S{{O}_{4}} \right]Br\] gives   yellow precipitate \[\left( AgBr \right)\] with \[AgN{{O}_{3}}(aq)\].
