The degree of dissociation (α) of a weak electrolyte, AxBy is related to van't Hoff factor (i) by the expression:
1. α=x+y+1i-1
2.α=x+y-1i-1
3. α=i-1x+y+1
4. α=i-1x+y-1
Van't Hoff factor (i) = Observed Colligative PropertyNormal Colligative Property
AxBy1-α→xA+yxα+yB-xyα
Total Moles = 1-α+xα+yα = 1-αx+y-1
i=1+αx+y-11
⇒α=i-1x+y-1
