The deep red colour of `Fe(SCN)_3` and `Fe(SCN)_4^(ɵ)` is destroyed by addition of :

A

`F^(ɵ)`

B

`CN^(ɵ)`

C

`SCN^(ɵ)`

D

`Fe^(ɵ)`

Text Solution

Verified by Experts

The correct Answer is:
a
Because the complex `[FeF_6]^(3-)` is formed.

The deep red colour of Fe(SCN)_6^(3-) and is destroyed by addition of

What is te coordination number of Fe in [Fe(EDTA)]^(ɵ) ?

Iron (+II) is one of the most important oxidation states, and salts are called ferrous salts. Most of Fe(+II) salts are pale green and contain [Fe(H_(2)O)_(6)]^(2+) ion. Fe(+II) compounds are easily oxidised by air and so are difficult to obtain pure Fe^(2+) form many complexes like K_(4)[Fe(CN)_(6)] K_(3)[Fe(CN)_(6)] is used in the detection of Fe^(2+) ion with which it gives a deep blue colour. This colour is due to the formation of

Two solution (A)containing Fecl_(3)(aq) and(B) semipermeable membrance as shown below.If FeCl_(3) on reaction with K_(4)[Fe(CN)_(6)] ,produces blue colour of Fe_(4)[Fe(CN)_(6)] , the clue colour will be noticed in : |((A),,(B)),(FeCl_(3),,K_(4)[Fe(CN)_(6)])|
