Find out the oxidation states of two types of Fe atoms in Fe_(4)[Fe(CN)_(6)]_(3) and reqrite the formula in stock notation form |
|
Answer» SOLUTION :From our knowledge of COORDINATE complex we know that the species `Fe_(4)` which lies outside the complex ion I.e `[Fe(CN)_(6)]_(3)` is the +ve PART while the complex ion itself is the -ve part in other words the +ve charge on 4 fe atoms ouside the ocordination spher is balanced by the -ve charge on the complex ion since fe has two oxidationstates i.e +2 and +3 and oxidation number of `CN^(-)=-1 THEREFORE` Fe in the complex ions has an O.N of +2 while the fe atoms outside the coordination spere have an O.N of +3 thus the stock notation for `Fe_(4)[Fe(CN)_(6)]_(3)` is `Fe_(4)[Fe^(II)(CN)_(6)]_(3)` |
