Express this “thresholdconcentration” in mol L-1.4. You wish to purify 10.0 grams compound A, which is contaminated with O.12 grams of B by recrystallization from water. Assuming the water solubility table below, answer the following questions: Solubility at 20°C (g/100 mL) Solubility at 100°C (g/ 100mL) Compound A Compound B 0.25 15.0 0.30 1.00 (a) What volume of boiling water is required to dissolve all of compound A? (b) Upon cooling to 20°C, how many grams of compound A should crystallize? (c) Do you expect compound A to be pure or is some of compound B likely to crystallize too?
