Arrange the complexes `CoCl_3. 6NH_3, CoCl_3. 5NH_3, CoCl_3. 4NH_3` and `CoCl_2 . 3NH_3` in the descending order of conductivity of their aqueous solutions.

Text Solution

Verified by Experts

Aqueous solutions containing one mole of `CoCl_3 . 6NH_3 , CoCl_3 . 5NH_3 , CoCl. 4NH_3` and `CoCl_3. 3NH_3` gives respectively 4,3,2 and zero moles of ions. Thus the conductivity order is `CoCl_3 . 6NH_3 gt CoCl_3 . 5NH_3 gt CoCl_3. 4NH_3 gt CoCl_3 . 3NH_3` . Aqueous solution of `CoCl_3. 3NH_3` does not possess any ions and it is non conductor of electricity . `CoCl_3. 3NH_3` is a non electrolyte .
