About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
