Iron cannot form complexes with ammonia because

A

In alkaline solution, iron salts are precipitated as their hydroxides which are insoluble in excess of alkali

B

In acid solutions, `NH_(3)` cannot form complex because of protonation it changes to `NH_(4)^(+)` ion which have no donar site.

C

In the presence of ammonia, iron nitrides are formed

D

In solution aqua complexes of iron salts are produced which protects the ions of iron.

Text Solution

Verified by Experts

The correct Answer is:
A, B
