Question
Which method can be used to distinguish [Co(NH3)6][Cr(NO2)6] and [Cr(NH3)6][Co(NO2)6]
Options
A.by measurement of their conductivity
B.by titration method
C.by precipitation method with AgNO3
D.by electrolysis of their aqueous solutions
Solution
In one case, on electrolysis of aqueous solution the complex ion of cobalt
[i.e.,{Co(NH3)6}3+] of the complex [Cr(NH3)6][Co(NO2)6] moves towards cathode(i.e., negative electrode) and on this electrode finally cobalt would be deposited. In another case, on electrolysis of aqueous solution, the complex ion of chromium
[i.e.,{Co(NH3)6}3+] of the complex [Cr(NH3)6][Co(NO2)6] moves towards cathode(i.e., negative electrode) and on this electrode finally cobalt be deposited.
