  11. Using Table G • 1. How many grams of potassium nitrate saturates 100 mL water at 60°C? • 2. Could you dissolve 130 g potassium nitrate into 100 mL of this water? • 3. Could you dissolve 40 g NaCl into 100 mL water at 70 °C? • What’s the saturation level for sodium chloride in 100 mL of 70 °C aqueous solution? • THINK hard, look hard, write down 4 answers

  12. 1. How many grams of potassium nitrate saturates 100 mL water at 60°C?About 107 grams • 2. Could you dissolve 130 g potassium nitrate into 100 mL of this water?No, it’s saturated by 107 grams • 3. Could you dissolve 40 g NaCl into 100 mL water at 70 °C?No, it’s saturated at 38 grams • What’s the saturation level for sodium chloride in 100 mL of 70 °C aqueous solution?About 38 grams

  13. Assume you have a saturated 100 mL aqueous solution of KClO3 at 50°C. What happens if you cool it to 45°C? Cool to forty Start at fifty

  14. Assume you have a saturated 100 mL aqueous solution of KClO3 at 50°C. What happens if you cool it to 45°C? Cool to forty Only 15 grams KClO3 fits at this cooler temperature Start at fifty 22 grams of KClO3 fits into solution. 7 grams precipitates out of solution.

  15. Easy question first, then another, then a harder one. Assume you have a 100 mL saturated solution of NaNO3 at 20°C, and you warm it up to 50°C. How much more solute will be able to dissolve?How many grams of ammonia will dissolve into 100 mL water at 90°C? How many grams of ammonia will dissolve into just 40 mL water at the same temperature?

  16. Assume you have a 100 mL saturated solution of NaNO3 at 20°C, and you warm it up to 50°C. How much more solute will be able to dissolve?At 50 degrees about 115 g At 20 degrees about 88 g 27 more grams could dissolve into the warmer solutionHow many grams of ammonia will dissolve into 100 mL water at 90°C? How many grams of ammonia will dissolve into just 40 mL water at the same temperature?

  17. Assume you have a 100 mL saturated solution of NaNO3 at 20°C, and you warm it up to 50°C. How much more solute will be able to dissolve?At 50 degrees about 115 g At 20 degrees about 88 g 27 more grams could dissolve into the warmer solutionHow many grams of ammonia will dissolve into 100 mL water at 90°C?10 grams How many grams of ammonia will dissolve into just 40 mL water at the same temperature? Ammoniawater 10 g100 mL X g40 mL 90°C = 100 x = 400 X = 4 g ammonia

  18. How many grams NaCl dissolves into 43 mL water at 90°C? How many grams sodium nitrate saturates 1000 mL water at 10°C?

  19. How many grams NaCl dissolves into 43 mL water at 90°C? NaClwater 40g100 mL X g43 mL 90°C 100 x = 1720 X = 17.2 grams = 17 grams with 2 SF

  20. How many grams sodium nitrate saturates 1000 mL water at 10°C? 80g100 mL X g1000 mL NaNO3water 10°C 100 x = 80000 X = 800 grams

  21. How many grams KCl saturates 875 mL water at 10°C? How many grams sodium nitrate dissolve into 1420 mL water at 50°C? How many grams ammonium chloride dissolve into 25 mL water at 70 °C?

  22. How many grams KCl saturates 875 mL water at 10°C? KClwater 30 g100 mL X g875 mL 10°C 100 X = 26250 X = 262.5 = 263 g 3 SF

  23. How many grams sodium nitrate dissolve into 1420 mL water at 50°C? NaNO3water 115 g100 mL X g1420 mL 50°C 100 X = 163,300 X = 1633 = 1630 g 3 SF

  24. How many grams ammonium chloride dissolve into 25.0 mL water at 70 °C? 15.5 = 16 grams with 2 SF NH4Clwater 62 g100 mL X g25.0 mL 70°C 100 X = 1550 X = 15.5 g ammonium chloride
