Use a different colored pencil for each compound. Compound Ba(OH) 2 CuSO 4 KCl NaNO 3 Solubility (g/100 g of water) 180 160 140 120 100 80 60 40 20 0 Directions: Use the information in the table and your graph to answer the following questions. 1. At about what temperature will 100 g of water dissolve equal amounts of potassium chloride and barium hydroxide? 2. At about what temperature will 37 g of both copper(II) sulfate and potassium chloride dissolve in 100 g of water? 0˚C 23.10 3. If 100 g of sodium nitrate are dissolved in 100 g of water at 60°C, is the solution formed saturated, unsaturated, or supersaturated? 4. If 32 g of copper (II) sulfate are dissolved in 100 g of water at 20°C, is the solution produced saturated, unsaturated, or supersaturated? 20˚C 60˚C 100˚C 1.67 3.89 20.94 101.40 28.0 73.0 Solubility in g/100 g Water 32.0 34.2 87.6 Temperature 61.8 45.8 122.0 114.0 56.3 180.0 0 20 40 60 80 100 120 Temperature ˚C Copyright © Glencoe/McGraw-Hill, a division of the McGraw-Hill Companies, Inc.
