Key Concepts

Chapter Summary

• Solutions consist of solutes and solvents. • Solutions can be dilute or concentrated, and saturated, unsaturated, or supersaturated. • The concentration of a solution is the amount of solute dissolved in a specific amount of solvent.

• The concentration of a solution can be described in qualitative and quantitative terms. (8.1) • Solutes and solvents can be identified in various kinds of solutions. (8.1) • Solubility is affected by temperature, type of solute or solvent, particle size, and stirring. (8.2) • Solutions and mechanical mixtures are separated in different ways. (8.3) • Water is sometimes known as the universal solvent. (8.1) • Gases dissolve more in colder water than in warmer water • Water is sometimes known as the universal solvent.
