Question

1. In K4[Fe(CN)6],Fe is in the form of

(A) An atom
(B) Neutral complex (C) Cationic complex (D) Anionic complex​

Answer 1

Answer:

it is in the form of neutral compound....

because it's counter ion make it neutral.....

Answer 2

Answer:

In K₄[Fe(CN)₆], Fe is in the form of an anionic complex.

Explanation:

The complex sphere of an anionic complex compound has a negative charge.

 K₄[Fe(CN)₆] → 4K⁺ + [Fe(CN)₆]⁴⁻

When the complex is anionic the name of the central metal atom or ion ends with the suffix ate and is followed by oxidation state written in Roman numerals and enclosed within brackets.

The central metal ion present in the complex K₄[Fe(CN)₆], will be named ferrate(II).
