Question
Barium ions, CN- and Co2+ form an ionic complex. If that is supposed to be 75% ionised in water with vant Hoff factor (i) equal to four, then the coordination numbers of Co2+ in the complex can be:
Options
A.6
B.4
C.6 & 4 both possible
D.5
Solution
α = 
∴ x = 5 ∴ Complex is Ba3[Co(CN)5]2
∴ x = 5 ∴ Complex is Ba3[Co(CN)5]2Create a free account to view solution
