What is the solubility of potassium nitrate, KNO3at 70 ºC?,  | about 132 g/100 mL water |
At what temperature can 100 mL of water first dissolve 50 grams of potassium chloride?,  | about 80 ºC |
| Which compound is least soluble at 50 ºC?, | NaCl (sodium chloride) |
| Which compound is most soluble at 20 ºC?, | NaCl (sodium chloride) |
| Which compound is most soluble at 28 ºC?, | KNO3 (potassium nitrate) |
Which compound is probably a gas? Why?,  | Ce2(SO4)3 because its solubility decreases as the temperature of the water increases. |
| Which compound's solubility changes the least as the temperature changes?, | NaCl (sodium chloride) |
