In the separating funnel shown, two immiscible layers are formed after shaking. If the solute is more soluble in chloroform, which layer should be collected to obtain the solute?
Correct answer: B. Lower layer
- A. Upper layer
- B. Lower layer
- C. Both layers
- D. Neither
Explanation
Chloroform (denser) forms the lower layer; solute distributes there due to higher solubility.

About Experimental Techniques in Chemistry
Separation methods are selected according to differences in solubility, particle size, volatility and sublimation behaviour. Filtration and crystallisation separate insoluble or dissolved solids, sublimation isolates suitable volatile solids, distillation separates liquids by boiling point, and solvent extraction transfers a substance between immiscible solvents.
