When the solvent dissolves very little of solute, then__________________________?
Correct answer: A. Large quantity of solvent is required to extract the solute
- A. Large quantity of solvent is required to extract the solute
- B. Solvent of low freezing point should be used
- C. Solvent of low latent heat of vaporisation should be used
- D. Very small quantity of solvent is required
Explanation
If the solvent has low solubility for the solute, each unit of solvent extracts only a small amount. Consequently, a large quantity of solvent is needed to achieve the desired recovery.
