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?

Explanation

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+0.95 = 1.95
n=3 for `BaCl_2` , i=1+(3-1) `alpha` = 1+2 `alpha`
=1+1.9=2.9
The ratio of van.t Hoff factor for KCl and `BaCl_2`
=1.95 : 2.9 =1:1.51
