1. Compound X has a solubility in toluene of 18 mg per 100 mL at 20 °C, and a solubility of 0.64 g per 100 mL at 70 °C. You are given a sample of 0.48 g of compound X which is contaminated with 25 mg of compound Y. A. If compound Y is always soluble in toluene, describe in detail how you could separate Y from X. Would x now be pure? B. If compound Y has approximately the same values of...
