13.9: Freezing Point Depression and Boiling Point Elevation
2022年7月19日 · A mathematical equation is used to calculate the boiling point elevation or the freezing point depression. The boiling point elevation is the amount that the boiling point temperature increases compared to the original solvent. For example, the boiling point of pure water at \(1.0 \: \text{atm}\) is \(100^\text{o} \text{C}\) while the boiling ...
Freezing and Boiling Points - CliffsNotes
When calculating the change in freezing point or boiling point, the concentration of all the solute particles must be used, whether they are molecules or ions. The concentration of the ions in this solution of AlBr 3 is 1.072 molal, and this molality would be used to calculate Δ T f and Δ T b .
