Constructed Response Topic 7: Solutions
Set A: Solubility factors, temperature and pressure effects on solubility
Base your answers to questions 1 and 3 on the information below.
When cola, a type of soda pop, is manufactured, CO2(g) is dissolved in it.
On the set of axes to the right.
1. Label one of them “Solubility” and the other “Temperature.”
2. Draw a line to indicate the solubility of CO2(g) versus
temperature.

3. A capped bottle of soda contains CO2(g) under high pressure. 3.
When the cap is removed, how does pressure affect the
solubility of the dissolved CO2(g) ?
Set B : Effect of temperature of rate of dissolving, solubility factors, data interpretation
Base your answer to questions 4 through 6 on the information and table below.
A student conducts an experiment to determine how the temperature of water
affects the rate at which an antacid tablet dissolves in the water. The student
has three antacid tablets of the same size and composition. The student drops
one tablet into each of the three beakers containing 200. millimeters of water
at different temperature and measures the time it takes for each tablet to completely
dissolves. The results are shown in the table below.
