1.	Describe the method, which can be used to separate two compounds with different solubilities in a solvent S.
Answer» Solution :The fractional crystallisation method is used to separate two compounds with different solubilities in a solvent. Both COMPOUND dissolve in solvent and FORM hot SATURATED solution. Cool these solution. The compound which is less soluble is crystallise first. By filtration, separate the crystal which are of compound having less SOLUBILITY. Mother liquor solution contain more soluble compound. By concentratin of these solution convent it into saturated solution. Now cool the solution. So, crystallisation will take place and the crystal of less soluble compound will obtain. By filtration, separation. (Two compounds + solute) `overset(Delta)rarr` saturated solution
