Question
Barium ions, CN- and Co2+ form an ionic complex. If that complex is supposed to be 75% ionised in water with vant Hoff factor ′i′ equal to four, then the coordination number of Co2+ in the complex can be :
Options
A.Six
B.Five
C.Four
D.Six and Four both
Solution
i = 1 + α (n - 1) or 4 = 1 + 0.75 (n - 1)
∴ n = 5, so complex will be Ba3 [Co(CN)5]2.
∴ n = 5, so complex will be Ba3 [Co(CN)5]2.
