the compound will dissociate as 2 al3+ and 3so4^2-
so, total no of ions after dissociation = 2+3 =5
vant hoff factor = total no of ions after dissociation / before dissociation = 5/1 = 5
so, here the vant hoff factor will be 5 .

Al2(SO4)3 => 2Al3+ + 3SO42-
1 0 0 (initial)
0 2 3 (final after dissociation)
Van’t Hoff factor (i) = Moles after dissociaton/ Total initial moles
That is, (i) = (2+3)/1
Thus, (i)= 5
