    Complexes \[[Co{{(N{{H}_{3}})}_{5}}S{{O}_{4}}]\] Br and \[[Co{{(N{{H}_{3}})}_{5}}Br]S{{O}_{4}}\] 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] \[[Co{{(N{{H}_{3}})}_{5}}Br]S{{O}_{4}}\] gives white precipitate of \[BaS{{O}_{4}}\] with \[BaC{{l}_{2}}(aq)\] whereas \[[Co{{(N{{H}_{3}})}_{5}}S{{O}_{4}}]\] Br gives yellow precipitate (AgBr) with \[Ag\,N{{O}_{3}}(aq).\]
