Solution

ANSWER:

PAER (A)

As per the graph shown in the question it is clear to one that KNO₃ is totaly soluble in water and K₂SO₄ is partially soluble. For example at 30^oC approximately 42g of KNO₃ is dissolved in water, while at the same temperature only 12g of K₂SO₄ is dissolved.

(B) 35.7g of KNO₃ is dissolved in water. The solubility of KNO₃ at 0oC is 14g/100mL of water. So out of 35.7g of KNO₃ only 14.0g will dissolve in water and rest will crystalize out.

So the amount of KNO₃ that will crystalize out = 35.7g - 14.0g = 21.7g
