Coordination Compounds - Result Question 22
####24. Which of the following will exhibit maximum ionic conductivity?
[2001]
(a) $K_4[Fe(CN)_6]$
(b) $[Co(NH_3)_6] Cl_3$
(c) $[Cu(NH_3)_4] Cl_2$
(d) $[Ni(CO)_4]$
Show Answer
Solution:
- (a) The complex ion which give maximum ions in solution exhibit maximum ionic conductivity.
$ K_4[Fe(CN)_6] \to[Fe(CN)_6]^{-4}+4 K^{+} \to 5 \text{ ions } $
$[Co(NH_3)_6] Cl_3 \to[Co(NH_3)_6]^{3+}+3 Cl^{-} \to 4$ ions
$[Cu(NH_3)_4] Cl_2 \to[Cu(NH_3)_4]^{2+}+2 Cl^{-} \to 3$ ions
$[Ni(CO)_4] \to$ No ions
