Question

How to find the oxidation states of complexes

Answer 1

Answer:

Do you mean oxidation numbers in coordination complexes, e.g.  

[ F e ( C ≡ ) 6 ] 3 − ,  C o C l 3 − 6 ,  cr ( C O ) 6 ?

Explanation:

You have the starting complex, and its charge. Remove the ligands, with their associated charge, and examine the residual charge on the metal centre, which will be the oxidation state.

[ F e ( C ≡ N ) 6 [ 3 − → 6 × N ≡ C − + F e 3 , ferric ion

[ C o C l 6 ] 3 − → 6 × C l − +C o 3 + ,  Co(III) .  [ C r }C O ) 6 ] → 6 × C ≡O + C r  Cr(0)
