    Definition "the phenomenon that the boiling point of a liquid (solvent) rises when a solute is added to a solvent due to the fact that the vapour pressure ( IATE:1590631 ) of the solvent (above the resulting solution) becomes less than the vapour pressure above the pure solvent." Reference "Based on: Purdue University, Department of Chemistry, Boiling Point Elevation http://www.chem.purdue.edu/gchelp/solutions/eboil.html [20.1.2010]"
