The freezing-point depression of a 0.100 m MgSO4 solution is 0.225°C. Determine the experimental van't Hoff factor of MgSO4 at this concentration. (Kf of water is 1.86°C/m)

The experimental van't Hoff factor is 1.21

Explanation:

The expression for the depression in freezing point is given as:

where,

i = van't Hoff factor = ?

= depression in freezing point  = 0.225°C

= Cryoscopic constant  = 1.86°C/m

m = molality of the solution = 0.100 m

Putting values in above equation, we get:

Hence, the experimental van't Hoff factor is 1.21
