As we have learned

Complex Salt -

Do not dissociate completely when disssolved in water

- wherein

eg: K_{4}\left \left [ Fe\left (CN \right )_{6} \right ]\rightarrow 4K^{+}\left [ Fe\left ( CN \right )_{6} \right ]^{4-}

But do not give Fe^{2+} and  CN^{-} 
ions

 

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