Skill Sheet 21.2: Solubility Part 1 answers: 1. Insoluble means that no amount of this substance will dissolve in water at this temperature under these conditions. Chalk and talc are substances that do no interact with water molecules. It is possible that the bonds in chalk and talc molecules are nonpolar. 2. The degree to which a substance is soluble depends on the nature of the bonds and the size of the molecules in the substance. Molecules of sugar, salt, and baking soda are different with respect to the nature of the bonds and sizes of these molecules. Therefore, these molecules will each dissolve in water in different ways and to different degrees. 3. 205 g 4. 190 mL 5. 25 mL 6. 1 g Part 2 answers: 2. 72 grams 3. 10 ppt Substance Amount of substance in 200 mL of water at 25°C Saturated, unsaturated, or supersaturated? Table salt (NaCl) 38 grams unsaturated Sugar (C12H22O11 ) 500 grams supersaturated Baking soda (NaHCO3 ) 20 grams saturated Table salt (NaCl) 100 grams supersaturated Sugar (C12H22O11 ) 210 grams unsaturated Baking soda (NaHCO3 ) 25 grams supersaturated Page 47 of 57 Part 3 answers: 1. Graphs: 2. Gases A and B are less soluble in water as temperature increases. Solid A is more soluble as temperature increases. Solid B is slightly more soluble as temperature increases. 3. This question may be challenging for students. Temperature affects gas B most dramatically. The range of solubility values is large, ranging from one-tenth to five-thousandths. 4. Temperature affects the solubility of solid A more than it affects solid B. 5. Solid B 6. In fall and winter, when the weather turns cold, the water will have more dissolved oxygen. During the warmer months of the spring and summer the amount of dissolved oxygen in the water will decrease. Skill Sheet 21.2: Salinity and Concentration problems 1. Answers are: 4. Add 420 grams of salt to 1,580 grams of water. If the Place Salton Sea California Salinity 44 Salt in 1 L 44 Pure water in 1 L 956 dissolved salt does not bring the volume up to 2,000 mL, make a second batch of solution. Add the second batch to the first until you have two liters of solution. 5. 6 ppt Great Salt Lake Utah Mono Lake California Pacific Ocean 280 210 87 280 210 87 720 790 913 6. 45 grams 7. 2 ppm 8. 5 ppb 9. yes; yes 10. 50,000 times more sensitive
Skill Sheet 21.3: Calculating pH 1. Answers: a. 10 –2 > 10 –3 b. 10 –14 < 10 1 c. 10 –7 = 0.0000001 d. 10 0 < 10 1 2. Answers: a. acid b. neutral c. base Skill Sheet 22.1: Groundwater and Wells Making predictions: a. 1,3 b. 3 c. No, because water can’t pass through the cling wrap/foam layer. Thinking about what you observed: a. 1,3; yes b. 3; yes c. Aquiclude d. Aquifer e. No, because the well is below the aquiclude. Yes, hypothesis was correct. Skill Sheet 22.2: The Water Cycle Part 1 answers: A. condensation B. precipitation C. percolation D. groundwater flow E1. evaporation E2. evaporation F. transpiration G. water vapor transport. Skill Sheet 24.1: Period and Frequency 1. 0.05 sec 2. 0.005 sec 3. 0.1 Hz 4. 3.33 Hz 5. period = 2 sec; frequency = 0.5 Hz 6. period = 0.25 sec; frequency = 4 Hz 7. period = 0.5 sec; frequency = 2 Hz Page 48 of 57 3. pH = 4 4. pH 5; weaker acid 5. pH 7; Water is neutral and has an equal number of H+ and OH- ions. 6. 10 –11 ; base 7. 1 × 10 –8.4 8. The product with lemon juice contains a greater concentration of acid which would mean that it might be a better cleaning solution than the cleaner with the weaker acid, vinegar. f. The surface contamination would move toward well #1. If well #2 was being pumped, it would not have an effect on the movement of surface contamination because it is located below the aquiclude. g. Well #3 would possibly be able to provide water. It depends on how low the water table became. h. It might pull in salt water from the ocean. That is a form of contamination. i. Answers will vary. Sample answer: Look up how low the water table got during the worst drought of the last 100 years. Dig the well a little lower than that level. Part 2 answers: 1. evaporation—The Sun’s heat provides energy to enable water molecules to enter the atmosphere in the gas phase; transpiration—The Sun’s energy makes photosynthesis possible, which in turn causes plants to release water into the atmosphere in a process known as transpiration. 2. Wind pushes water in the atmosphere to new locations, so that the water doesn’t always fall back to Earth as precipitation in the same spot from which it evaporated. 3. Gravity causes water to run down a mountain toward the coast, and causes water droplets to fall to Earth as precipitation. Gravity is also the primary force that moves water from Earth’s surface through the ground to become groundwater. 8. Answers are: a. 5 sec b. 5 sec c. 0.2 Hz 9. Answers are: a. 120 vibrations b. 2 vibrations c. 0.5 sec d. 2 Hz
