Catalytic properties    of Transition Element-

:- some of the transition metals and their salts act as catalyst . For example, finely divided iron act as a catalyst in Haber's process for the manufacturer of ammonia. Finely divided nickel is used as a catalyst in the hydrogenation of oil to fat in the manufacturer of vegetable ghee . Decompression of bleaching powder solution is catalysed by Cobalt salt . MnO² is used as a catalyst in the decompression of H²O² solution in contact process .

   The catalytic power is probably due to the use of (n_1) d-orbitals or due to the Formation of some interestital compound which absorb and activate the reacting substance.

Coordination sphere and Ionisation sphere all about this

Coordination sphere                          and Ionisation sphere > In the complex , the central metal ion along with the ligand attached to it . It is always written in a square bracket [ ] . This part of the complex is called - coordination sphere The species present in the co ordination sphere are non ionisable . The portion present outside of the square bracket is called  - ionisable sphere . The species present in ionisable sphere it is ionisable.   For example - 1: In the complex [Cu ( NH3 ) 4 ] SO4 , the part [Cu(NH3)4]2+ is called coordination sphere . 2: In complex K4 [Fe(CN)6] , the part [Fe(CN)6 ⁴-] is called coordinate sphere and K+ constitutes ionisable sphere .
