Lesson Plan: Solubility Chemistry
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to define and measure the solubility of a substance and explain its dependency on solvent, temperature, and pH.
Objectives
Students will be able to
- define the solubility of a substance and understand the difference between a saturated and an unsaturated solution,
- recall the general rules for the solubility of common substances in water,
- explain how the solubility of solids and gases varies with heat,
- explain how solvent, pH, particle size, and stirring affect solubility in terms of interactions and acid–base reactions,
- define precipitate and predict whether one will form when two solutions are mixed together,
- understand and interpret solubility graphs and make predictions using them,
- calculate the solubility of a substance from the masses of the solid and water.
Prerequisites
Students should already be familiar with
- compounds and mixtures.
Exclusions
Students will not cover
- acid–base reactions,
- crystallization,
- water of crystallization,
- solubility products.
