10. Consider the following table of compound and their solubility in hot and cold water, and in hot and cold ethanol: Solubility in grams per liter (g/L) Cold Water 3.53 23.6 Compound Hot Water 5.11 Hot Methanol Cold Methanol 14.6 12.8 0.81 26.4 18.9 1.36 55.2 C 7.14 1.52 0.012 D 21.3 0.76 51.7 a. Which of the compound(s) above could be effectively recrystallized from methanol? Explain your answer. b. Assume you were given 5 g of a mixture of C and D (unknown ratio). Devise a plan to separate and purify them. Hint: methanol has lower boiling point (64.7 °C) than water (100 °C) and easily evaporated under low pressure.
