Elevation of Boiling point - Depression of freezing point Colligative properties by Tariq Pathan

Elevation of Boiling point - Depression of freezing point Colligative properties by Tariq Pathan Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope. Depression of freezing point: Freezing-point depression is a drop in the temperature at which a substance freezes, caused when a smaller amount of another, non-volatile substance is added. Examples include adding salt into water (used in ice cream makers and for de-icing roads), alcohol in water, ethylene or propylene glycol in water (used in antifreeze in cars), or the mixing of two solids such as impurities into a finely powdered drug.
