Elevation of boiling point

  • Increase in temperature increases the vapour pressure of a
  • A liquid boils at atemperature where the vapour pressure is equal to the atmospheric
  • Vapourpressure of the solvent decreases in the presence of non-volatile solute.
  • The boilingpoint of a solution is always higher than that ofthe boiling point of the pure solvent in which thesolution is prepared as.
  • The elevation ofboiling point also depends on the number ofsolute molecules rather than their nature.
  • The increase in the boiling point = ΔTb = Tb – Tb0. This is known as elevation of boiling point.

Tb= boiling point of pure solvent

Tb= boiling point of solution
