Vedclass · Accepted Answer

The complex ion carries $-4$ charge

Vedclass · Answer

(A) The complex is $Na_4[Fe(CN)_6]$.$1$. The complex ion is $[Fe(CN)_6]^{4-}$,which carries a $-4$ charge.$2$. To find the oxidation state of $Fe$ $(x)$:$x + 6(-1) = -4$$x - 6 = -4$$x = +2$$3$. The coordination number $(C.N.)$ of $Fe$ is determined by the number of ligands attached,which is $6$ ($CN^-$ is a monodentate ligand).Therefore,the statement that the complex ion carries a $-4$ charge is true.

Which among the following statements is true about $Na_4[Fe(CN)_6]$?
