Topics in Solutions

1

Components of a Solution

  • A solution is a homogeneous mixture of two or more substances.
  • Solute is the component that dissolves in the solvent.
  • Solvent is the component in which the solute dissolves and has the same physical state as the solution.
2

Concentration of Solutions

  • Different ways to express concentration: molarity, molality, normality, mole fraction, and mass percentage.
  • Molarity depends on volume and changes with temperature.
  • Molality is based on mass and does not change with temperature.
3

Types of Solutions and Henry's Law

  • Nine possible combinations of solute and solvent states exist, but common ones are solid in liquid, gas in liquid, and liquid in liquid.
  • Gases dissolve in liquids; solubility increases with pressure and decreases with temperature.
  • Henry’s Law: the solubility of a gas is directly proportional to its partial pressure.
4

Vapour Pressure and Raoult's Law

  • Vapour pressure is the pressure exerted by vapours in equilibrium with the liquid.
  • Raoult’s Law: partial vapour pressure of each component is proportional to its mole fraction.
  • For non-volatile solutes, vapour pressure of solution is less than pure solvent.
