Practice objective / multiple choice question 37 from the 2019 Gce Model Questions Vol1 Chemistry examination.
The solubility of potassium nitrate, \(\text{KNO}_{3}\), is 38 g per 100 g water at 25 °C and 13 g per 100 g water at 0 °C. A 50.0 g sample of \(\text{KNO}_{3}\) is dissolved in 200 g of water at 25 °C and the solution is then cooled to 0 °C. Assuming no crystallisation occurs until the solution becomes saturated, how many grams of \(\text{KNO}_{3}\) will crystallise out on cooling?
