CompoundsLesson Objectives
- Explain how water acts as a solvent.
- Describe the process of dissolution and what this looks like at the molecular and macroscopic level.
- Describe the process of dissociation and what this looks like at the molecular and macroscopic level.
- Define and give examples of solvents and solutes.
- Describe and give examples of chemical solutions.
Lesson Vocabulary
- aqueous solution: A homogeneous mixture in which the most abundant component is water.
- solution: A homogeneous mixture.
- solvent: The substance in a solution that is present in the largest amount.
- solute: All other substances in a mixture or solution.
- dissolution: The process where crystals in a molecule get smaller and smaller until the solution is transparent.
- soluble: A homogeneous mixture where a solute dissolves completely into a solvent.
- dissociation: The process of separating ions from one another.
- insoluble: A heterogeneous mixture where a solute does not dissolve completely into a solvent.
Check Your Understanding
