A solid mixture consists of 85.0% KNO 3 and 15.0% K 2 SO 4 , by mass.

Question:

A solid mixture consists of 85.0% KNO₃ and 15.0% K₂SO₄, by mass. A60.0 g sample of this solid is added to 130.0 g of water at 60 °C. Refer to Figure 14-10.

(a) Will all the solid dissolve at 60 °C?

(b) If the resulting solution is cooled to 0 °C, what mass of KNO₃ should crystallize?
