Solubility Curves Worksheet

Solubility Curves Assessment

Read each question carefully and answer to the best of your ability. Refer to your knowledge of solubility curves and related concepts.

1. Which of the following statements is generally true for the solubility of most solid solutes in water as temperature increases?

2. A solution containing the maximum amount of solute that can be dissolved at a given temperature is called a:

1. A solubility curve shows the relationship between   and the solubility of a solute in a given solvent.

2. When a solution is cooled, the solubility of most solid solutes  , which can lead to  .

1. All solubility curves show an increase in solubility with increasing temperature.

2. Pressure significantly affects the solubility of solid solutes in liquid solvents.

1. Describe what a solubility curve represents and how it is used.

2. Explain the difference between an unsaturated, saturated, and supersaturated solution.

Use the hypothetical solubility curve below to answer the following questions.

1. According to the curve, approximately how many grams of solute can dissolve in 100 g of water at 40°C?

2. If 60 grams of this solute are dissolved in 100 g of water at 20°C, is the solution saturated, unsaturated, or supersaturated? Explain your reasoning.

Use the words below to complete the sentences.

1. The solubility of gases generally decreases with increasing   and increases with increasing  .

2. When a supersaturated solution cools, excess solute often undergoes  .
