Freezing point and boiling point
WebThe boiling point is raised by 0.5 degrees Celsius for water with 29.2 grams of salt dissolved in each kg of water. If your concentrations of salt are different, then you can scale the boiling point elevation and melting point depression predictions directly with the concentration. These numbers come from the CRC Handbook of Chemistry and ... WebΔTf = (1.86 C/m) × (0.6 m) × 3 = 3.348 C. The freezing point depression is the difference between the freezing point of pure water (0°C) and the freezing point of the solution: Freezing point of solution = 0 ° C − Δ T f = 0 ° C − 3.348 ° C = − 3.348 ° C. Therefore, the freezing point of the solution is -3.348°C.
