Question

Based on your results of the boiling point elevation and melting point depressions, what is the experimental van't Hoff factor (i) for each listed solution? How does that compare to the theoretical van't Hoff factor? (Please show work) Thanks!

Solutions:

- 3.0 m NaCl in water (Exp. Boiling: 106.8 C) (Exp. Freezing: -12.4 C)

- 3.0 m MgCl2 in water ( Exp. Boiling: 107.1 C) (Exp. Freezing: -16.1 C)

- 3.0 m AlCl3 in water (Exp. Boiling: 108.5 C) (Exp Freezing: -8.4 C)

- 3.0 m ethylene glycol in water (Exp Boiling: 104.1 C) (Freezing: -7.8 C)
