A mixture contains two organic solids, A and B. The solubilities o f A and B in water are 12 g per 100 ml. and 3 g per 100 ml respectively. How will you separate A and B from this mixture?

Text Solution

Verified by Experts

The two components can be separted by fractional crystallisation. When the saturated hot solution of his mixture is allowed to cood, the more soluble compound, B crystallises out first leaving the more soluble compound, A in the mother liquor. The mother liqours is then concentrated and allowed to cool when the compound A crystallises out.
