Question

What is the Van’t Hoff factor? How does is modify the equation for the elevation of boiling points?

Solution

The Van’t Hoff factor is expressed as

i = \frac{observed colligative property}{Normal colligative property} or i = \frac{Normal molecular of the solute}{Observed molecular mass of the solute}

Modified equation for the elevation of boiling point
ΔT_b = i K_bm
