matt did an experiment to study the solubility of two substances. he poured 100 ml of water at 20 °c into each of two beakers labeled a and b. he put 50 g of substance a in the beaker labeled a and 50 g of substance b in the beaker labeled b. the solution in both beakers was stirred for 1 minute. the amount of substance left undissolved in the beakers was weighed. the experiment was repeated for different temperatures of water and the observations were recorded as shown.
part 1: which, if any, substance is soluble in water?
part 2: explain how the data you determine solubility for both substances for temperatures 20 °c to 80 °c.
