Q. A solution of potassium ferrocyanide would contains-ions
A) 2
B) 3
C) 4
D) 5
Explanation
(d)
Potassium ferrocyanide $K_{4}\lbrack Fe(CN)_{6}\rbrack$ will ionize as
$K_{4}\left\lbrack Fe(CN)_{6} \right\rbrack \rightleftharpoons 4K^{+} + \left\lbrack Fe(CN)_{6} \right\rbrack^{4 -}$
So, it will give five ions in solution
