If extent of dissociation of both KCl and `BaCl_2` of some concentrations with identical value of `alpha` as 0.9, what is the ratio of their van't Hoff factors?

Text Solution

Verified by Experts

van.t Hoff factor is given as, `i = (1 + (n - 1))/(1) alpha`
`n = 2` for `KCl , i = 1 + (2 - 1) alpha = 1 + alpha = 1 + 0.9 = 1.9`
`n = 3 ` for `BaCl_2 , i = 1 + (3 - 1) alpha = 1 + 2 alpha = 1 + 1.8 = 2.8`
The ratio of van.t Hoff factors for KCl and `BaCl_2 = 1.9 - 2.8`
`= 1 : 1.473`.
