When, common salt is dissolved in water ,it’s boiling point-: a. Increases. b. Decreases. c. Remains constant d. None .
Solution
There is elevation in boiling point of solution when the solute is added to it.
When a non-volatile solute is added to a solvent, the vapour pressure of the resulting solution is lower than that of the pure solvent. Therefore, a greater amount of heat must be supplied to the solution for it to boil. This increase in the boiling point of the solution is the boiling point elevation.
