1. The solubility of Aspirin is 0.4g/100 mL in water and 10g/100 mL in diethylether. What is the required volume of ether in order to extract 80% of the Aspirin dissolved in 200mL of water in a single extraction?
2. Give a scenario where liquid-liquid extraction is valid as a separation technique between two components. Name the two components, and the two solvents and explain the procedure in a sentence.
3. Mention two important properties that the extraction solvent must have.
