What is the elevation of boiling point
  • 1 answers

Yogita Ingle 6 years, 8 months ago

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

Tb0 = boiling point of pure solvent

Tb0 = boiling point of solution
