Question

\(\mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]\) is a

(a) double salt

(b) normal salt

(c) complex compound

(d) none of these

Answer 1

Correct option is (c) complex compound

K₄[Fe(CN)₆] is complex salt. Complex ion, [Fe(CN)₆]⁴⁺ will be represented in square bracket and is called coordination entity. This will exist as a distinct entity. It does not dissociate into simple ions.

Simple salts and double salts will dissociate into its simple ions.
