Which of the following will exhibit maximum ionic conductivity?
- K4[Fe(CN)6]
- [Co(NH3)6]Cl3
- [Cu(NH3)4]Cl2
- [Ni(CO)4]
Answer
(1) K4[Fe(CN)6]
Solution
Ionic conductivity increases with the number of ions given in solution.
K4[Fe(CN)6] 4K+ + [Fe(CN)6]4- 5 ions
[Co(NH3)6]Cl3 [Co(NH3)6]3+ + 3Cl- 4 ions
[Cu(NH3)4]Cl2 [Cu(NH3)4]2+ + 2Cl- 3 ions
[Ni(CO)4] is neutral no ions
K4[Fe(CN)6] shows the maximum ionic conductivity.
