What to Focus On

  • A solution consists of two components: solute and solvent.
  • Solute is the component that dissolves in the solvent.
  • Solvent is the component in which the solute dissolves and usually determines the physical state of the solution.
  • Molarity (M) = moles of solute / volume of solution in litres.
  • Molality (m) = moles of solute / mass of solvent in kg.
  • Normality (N) = gram equivalents of solute / volume of solution in litres.
  • Nine types of solutions exist based on physical states of solute and solvent.
  • Common types: solid in liquid, liquid in liquid, gas in liquid.
  • Miscibility: complete, partial, or immiscible.

Common Mistakes to Avoid

Molarity and molality are the same; they both measure concentration, so they can be used interchangeably.

When a non-volatile solute is added to a solvent, the vapour pressure increases because more particles are present.

All solutions obey Raoult’s law, and deviations are rare.

Memory Tips

Components of a Solution: Solute and Solvent

Molarity (M) = moles of solute / volume in litres

Molality (m) = moles of solute / kg of solvent

Normality (N) = Molarity × n-factor
