WebThis chemistry video tutorial provides a basic introduction into colligative properties such as boiling point elevation, freezing point depression, osmotic pressure, and vapor pressure. WebJun 16, 2016 · Once the molality of the solute is determined, the boiling point of the solution could be determined. The change in the boiling point is determined using the following formula: ΔT = Kb × m ×i Where Kb is the boiling point elevation constant for water. Kb = 0.510°C ⋅ Kg ⋅ mol−1 ΔT = Kb × m ×i m ΔT = Kb × m'
When an impurity or a solute (non-volatile) is added to a liquid that is being boiled, its Boiling Point will increase. This indicates that solutions tend to have a higher Boiling Point as compared to pure solvents. For instance, if you add non-volatile impurities like some sugar or a dash of salt to boiling water, its … See more We know that pure water boils at 100°C at 1 atm pressure, but an interesting thing happens to the Boiling Point if we add a small amount of salt to that water.
