A solid mixture consisted of equal parts by weight of benzoic acid, acetanilide and
copper sulfate. 1.80 g of this mixture was dissolved in 110 mL of boiling water and
slowly cooled to 0 °C. Determine the composition and percentage purity of the crystals
that formed. [Solubilities of benzoic acid, acetanilide and copper sulfate at 0 °C are
1.70, 5.30 and 316 g per litre, respectively.]
