Question

An aqueous solution contains two solutes, A and B. A is soluble in hexane, B is not. Hexane is liquid at room temperature and does not mix with water. The density of hexane at room temperature is 0.7 gdm-3. Describe, giving full practical details, how you would produce a pure sample of solid A.

Answer 1

You need to read about extractions. Since A is soluble in hexane and B is not, you extract A with hexane (go through perhaps 2-3 extractions), then evaporate the hexane to provide pure solid A.

Answer 2

h2o+c5r

Answer 3

square root of 58*7=20.149441
