A 500 cm³ volume of acetonitrile contains 0.154g of CuCl₂ for which the distribution
ratio into chloroform is 5.20. If 50 cm³ of chloroform is used for each extraction, how
many extractions are required to remove 95%?
Expert Solution

Step 1: Introduce concept
The question is based on solvent extraction. It uses the principle of nernst distribution law. It states that a solute distributes itself between two immiscible solvents in such a manner that concentration of solute remains constant in both the solvents at constant temperature.
