Question 9
Camille the chemist is given a mixture of two liquids A and B and the following table showing their properties:
A: density 0.79 g/mL; freezing point −98 °C; boiling point 65 °C; colorless; completely miscible in water and acetone.
B: density 0.97 g/mL; freezing point −95 °C; boiling point 110 °C; colorless; solubility 0.53 g/L in water, completely miscible in ethanol.
What is the best separation method should you use to purify the mixture?
