Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following statements best defines solubility?
The ability of a substance to conduct electricity.
The maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.
The rate at which a solute dissolves in a solvent.
The process of a solid turning directly into a gas.
2. Increasing the temperature of a solvent generally has what effect on the solubility of a solid solute?
Decreases solubility
Increases solubility
Has no effect on solubility
Causes the solute to precipitate
1. A solution that contains the maximum amount of solute that can be dissolved at a given temperature is called a solution.
2. The 'like dissolves like' rule states that polar solvents tend to dissolve solutes, and nonpolar solvents tend to dissolve solutes.
3. The solubility of gases in liquids generally as temperature increases.
1. Explain why sugar dissolves faster in hot tea than in cold tea.
2. Describe the difference between a saturated and an unsaturated solution.
1. Agitation (stirring) increases the solubility of a solute.
True
False
2. Pressure significantly affects the solubility of solid and liquid solutes.
True
False
1. The solubility of potassium nitrate (KNO₃) at 20°C is 32 g per 100 g of water. If you dissolve 25 g of KNO₃ in 75 g of water at 20°C, is the solution saturated, unsaturated, or supersaturated? Justify your answer.
