Solution • A homogeneous mixture of two or more substances in a single phase • Particles are thoroughly mixed and remains mixed indefinitely • Components of a solution • Solvent: does the dissolving; the larger amount • Solute: is being dissolved; the smaller amount Chapter 12 Section 1 Types of Mixtures p. 401-406
Liquid and solid solutes p. 402 Chapter 12 Section 1 Types of Mixtures p. 401-406
Solute-Solvent Combinations • Solutes and solvents can be any state of matter. • Look at page 402 for examples • Alloys – solid solutions of metals p. 402 Chapter 12 Section 1 Types of Mixtures p. 401-406

Electrolytes & Nonelectrolytes • Electrolyte – a substance that dissolves in water to give a solution that conducts electric current • Ionic compounds and highly polar molecules form electrolytes • Nonelectrolytes – a substance that dissolves in water to give a solution that does not conduct electricity Chapter 12 Section 1 Types of Mixtures p. 401-406
