The solubility of a substance is 30 g per 100 mL of water at room temperature, 50 g per 100 mL of water at 80 ∘C. A student mixed 40 g of this substance with 100 mL of water at room temperature (stage 1), and then heated the mixture to 80 ∘C (stage 2). The mixture is then slowly cooled down to room temperature without any precipitation (stage 3). Finally, the student added a small crystal to the mixture and saw precipitation took place. This mixture is    supersaturated at stage 2   heterogeneous at stage 1   homogeneous at stage 4   saturated at stage 3

Q2. You want to purify 10 grams of benzoic acid that has been contaminated with 0.2 g of salicylic acid. You are given the following data: Solubility in water at 20 °C Solubility at 100 °C (g/10 ml) Compound (g/10 ml) Benzoic Acid 0.029 0.680 Salicylic Acid 0.029 0.22 0.680 6.67 a) What volume of Boiling water is needed to dissolve the 10 g of benzoic acid? (show calculations) b) How much benzoic acid will crystallize after cooling to 20 °C (show calculations) c) Will any salicylic acid crystals form? Why or why not? (show calculations/ reason for answer) d) What is the maximum amount of benzoic acid that could be recovered in the first crop of this recrystallization? (Show calculations)

30jud to 28AM basu mw 5. Sodium carbonate is a reagent that may be used to standardize acids in the same way that you have used KHP in this experiment. In such a standardization it was found that a 0.498-g sample of sodium carbon- ate required 23.5 mL of a sulfuric acid solution to reach the end point for the reaction.
