Question
16. Refer to the plot below to answer this question. A solution is prepared by dissolving 40 g of KClO3 in 100 mL H2O at 90 degree C. The solution is that slowly cooled to 50 degree C without evaporating any of the water. No visible change to the solution is observed. Which statement(s) about the solution at 50 degree C arc true? i. The solution is unsaturated. ii. The solution is supersaturated. iii. If more KCIO3(s) solid is added to the solution it will dissolve. A. i only B. ii only C. iii only EL i and ii E. i and iiiExplanation / Answer
From the graph it is very clear that the solution is super saturated because at 50oC the salt disolution for 100ml water is below 20g.
