MCQ
Number of ions present in ${K_4}[Fe{(CN)_6}]$
  • A
    $ 2$
  • B
    $10$ 
  • C
    $3$ 
  • ✓
    $ 5$

Answer

Correct option: D.
$ 5$
d
(d)${K_4}[Fe{(CN)_6}]$ is a complex salt. On ionisation it will dissociate in $4{K^ + }$ and ${[Fe{(CN)_6}]^{4 - }}$ ion. Hence, in ${K_4}[Fe{(CN)_6}]$ five ions are present.
