Elevation in boiling point of solution :-
When a non-volatile solute is added to a solvent, the boiling point of solution increases in comparision of pure solvent. The increase in boiling point of solution is called elevation in boiling point.
Suppose, B.P. of Pure solvent = To
B.P. of solution = T
:. Elevation in b.p. = ΔTb = T-T0
The elevation of boiling point is directly proportional to the molal concentration of the solut in the solution.
Thus, elevation of b.p. depends upon the number of moles of soiute, so, it is colligative property.
