Question
What are the characteristics of nonideal solutions.
✓

Answer

  • Nonideal solutions do not obey Raoult’s law over the entire range of concentrations.
  • The vapour pressures of these solutions may be higher or lower than ideal solutions.
  • These solutions exhibit two types of deviations from Raoult’s law namely (a) positive deviation and (b) negative deviation.
  • These solutions give azeotropic mixtures.
