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

Solute-Solvent Combinations
  • Solutes and solvents can be any state of matter.
  • Look at page 402 for examples
  • Alloys solid solutions of metals

Mixtures That Are Not Solutions
  • Suspensions particle settle out if not stirred
    constantly large particle size
  • Comparing solutions, colloids and suspensions on

Tyndall Effect
  • Occurs when light is scattered by colloidal
    particles dispersed in a transparent medium

Classes of Colloids
  • Foams and emulsions are types of colloids.
  • Table on page 404.

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
