Use the graph to the right to answer the next three questions: Solubility Curves 150 12. If 100 g of ammonium chloride is mixed with 400 mL of water at 50°C, the resulting solution would be: a. unsaturated b. saturated c. supersaturated d. more information is needed 140 KI 130 120 NANO, KNO 110 100 90 80 13. Approximately how much water is needed to dissolve 78 g of sodium chloride at 90°C? a. 31 mL HCI NH.CI. 70 60 b. 780 mL c. 312 mL d. 195 mL NH3 50 14. The solubility curves of NH3 and SO2 differ from the pattern of other solubility curves because: a. They are covalent rather than ionic compounds b. They are polar covalent compounds rather than non- polar covalent compounds c. They are gases d.
