WebPut ice in the cover of the pot. (You may have to replace the ice in the lid as it melts.) Turn on the burner to medium heat. You want the juice to boil moderately (not a rolling boil). Allow the pot to boil for 10 minutes or so (enough time to collect a sufficient amount of distillate for testing). WebIn this experiment, 5 consecutive readings indicate the freezing point for the solution. Similarly, the increase in boiling point, ΔT b (boiling point elevation) for a near ideal solution can be described by the equation: ΔT b = i K b · m Where i is the van’t Hoff factor, K b is the molal boiling point elevation constant of the solvent

WebThe Boiling point of a liquid is an important physical property. A liquid boiling point is the temperature when its vapor pressure is equal to the atmospheric pressure. Normally, the boiling point is measured at one atmosphere (101 kPa or 760 mmHg or 760 torr). Like melting points, boiling points are characteristic properties of pure materials.
