• 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

• 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
