Question
Which of the following is non-conducting ?
Options
A.CoCl3.6NH3
B.CoCl3.5NH3
C.CoCl3.4NH3
D.CoCl3.3NH3
Solution
(A) CoCl3 6NH3 
[Co(NH3)6]3++ 3Cl- (no. of ions = 4 & total electrical charges = 6)
(B) CoCl3.5NH3
[Co(NH3)5 Cl]2+ + 2Cl- (no. of ions = 3 & total electrical charges = 4)
(C) CoCl3.4NH3
[Co(NH3)4 Cl2]+ + Cl- (no. of ions = 2 & total electrical charges = 2)
(D) CoCl3.3NH3
[Co(NH3)3 Cl3] (neutral solution). It will not conduct electricity.
