Describe a simple test that will allow you to distinguish between the compounds: \[[Co{{(N{{H}_{3}})}_{5}}Br]S{{O}_{4}}\] and \[[Co{{(N{{H}_{3}})}_{5}}S{{O}_{4}}]Br\].

Answer:

                (i) Treat both the isomers separately with aqueous \[BaC{{l}_{2}}\] solution. The isomer which gives a white precipitate is \[[Co{{(N{{H}_{3}})}_{5}}Br]S{{O}_{4}}\]. (ii) Treat both the isomers separately with aqueous \[AgN{{O}_{3}}\]solution. The isomer which gives a light yellow precipitate is \[[Co{{(N{{H}_{3}})}_{5}}S{{O}_{4}}]Br\].
