  1. Rate of Solution and Solubility

  2. All of these can affect the rate at which a solid dissolves in water except — • A decreasing air pressure • B stirring the water • C increasing the temperature of the water • D using larger crystals of the solid

  3. All of these can affect the rate at which a solid dissolves in water except — • Adecreasing air pressure • B stirring the water • C increasing the temperature of the water • D using larger crystals of the solid

  4. A 0.2 g crystal of gypsum dissolves very slowly in 100 mL of water while the water is stirred. Which of these would cause the gypsum to dissolve faster? • F Decreasing the water temperature • G Stopping the stirring • H Lowering the air pressure • J Crushing the crystal

  5. A 0.2 g crystal of gypsum dissolves very slowly in 100 mL of water while the water is stirred. Which of these would cause the gypsum to dissolve faster? • F Decreasing the water temperature • G Stopping the stirring • H Lowering the air pressure • JCrushing the crystal

  6. Over time an open soft drink will lose carbonation (dissolved CO2). Which of these allows the CO2 to remain in solution the longest? • A Reduced air pressure • B Exposure to direct sunlight • C Increased air currents • D Cooler temperatures

  7. DCooler temperatures

  8. A recipe calls for 210 grams of sugar to be dissolved in 0.25 liter of water. After the mixture is stirred, some sugar crystals remain in the water. What can be added to the mixture to help dissolve the remaining sugar crystals? A Thermal energy B 2.0 g of baking soda C Ice cubes D 2.0 g of sodium chloride

  9. A 55%* B 12% C 24% D 10%

  10. At which temperature do KBr and KNO3 have the same solubility? A. 27°C  B. 48°C C. 65°C D. 80°C

  11. At which temperature do KBr and KNO3 have the same solubility? A. 27°C  B.48°C C. 65°C D. 80°C

  12. Power plants that discharge warm water into rivers have a negative effect on aquatic life. This is because the higher water temperature — A. increases the pressure of the river water B. increases the pH value of the river water C. decreases sediment solubility in the river water D. decreases the dissolved oxygen in the river water
