A solid substance A is soluble in water to the extent of 10 mg/mL of water at 25 °C and 100 mg/mL of water at 100 °C. You have a sample that contains 100 mg of A and an impurity B. a. Assuming that 2 mg of B is present along with 100 mg of A, describe how you could purify A if B is completely insoluble in water. b. Assume that 2 mg of the impurity B is present along with 100 mg of A, describe how you could purify A if B had the same solubility behavior as A. Would one crystallization produce pure A?
