Solubility Graph Reading
Name__________________ Hr___
Use the solubility graphs to answer the following questions.
1) What mass (in grams) of KCl will dissolve
in 100 grams of water at 70oC?
Effect of Temperature on the Solubility
of Various Salts in Water
2) How many more or fewer grams of NaCl
will dissolve in 100 grams of water at 70oC
than grams of KCl in #1?
3) What mass of of potassium nitrate will
dissolve in 100 grams of water at 70oC?
4) How much more potassium nitrate can be
dissolved in 100 g of water that has been
raised from 10oC to 50oC and originally
contained the saturated amount?
5) 25g of potassium nitrate are dissolved in
100 grams of water and the temperature
is raised to 90oC how much more chemical
is required to form a saturated solution?
6) If the temperature of potassium chloride is dropped from 100oC to 40oC how much chemical
will precipitate from solution if no supersaturated solution is formed?
7) Describe the relationship between temperature and solubility of a solid.
8) What mass of oxygen can be
dissolved in 100 grams of water
at 15 oC?
Effect of Temperature on Solubility
of Gas Molecules in Water
9) What mass of nitrogen monoxide
can be dissolved in 100 grams of
water at 30 oC?
10) How much more soluble in water
is carbon monoxide than nitrogen
gas at 10oC? At 40oC?
11) A. If a glass of soda is left outside on a hot summer day, what would you expect to happen
to the amount of dissolved carbon dioxide.
B. Why do you suppose some people prefer to drink carbonated beverages at very cold
temperatures?
