1. Experiments show that the solubility of alum in 25 mL of 1.4 M KOH plus 10 mL of 9 M H2SO4 is about 1.0 g at 1.0 °C and 1.7 g at 6.0 °C. Using your measured solution temperature, estimate the amount of alum left in your chilled solution. Alum left in solution: g 2. Does the amount of alum left in solution account for most of the difference between the maximum grams of alum and your experimental grams of alum? Explain.
