Question

How the isomeric complexes [Co(NH3)6][Cr(NO2)6] and [Cr(NH3)6][Co(NO2)6] can be distinguished from one another by

Solution

Correct option is

Electrolysis of their aqueous solutions

In former case, cobalt (III) complex [Co(NH3)6]3+ ion migrates toward the negative electrode where cobalt would be deposited. In the other case, chromium would be deposited at the negative electrode.
