Patrick 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 60 g of Substance A in the beaker labeled A and 60 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.
Mass of Undissolved Substance at Different Temperatures (gram) Substance: 20 °C 40 °C 60 °C 80 °C
A: 18 14 10 5
B: 60 60 60 60
Part 1: Which, if any, substance is soluble in water
Part 2: Explain how the data helped you determine solubility for both substances for temperatures 20 °C to 80 °C
