WebBoiling point elevation is the raising of a solvent's boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent's freezing point due to the addition of a solute. In fact, as the boiling point of a solvent increases, its freezing point decreases. An example of this would be the addition of ... WebMay 2, 2014 · mrpauller.weebly.com. May 2, 2014. You will need to use the equation: ΔTf = Kf mi. ΔTf = how much the freezing point is lowered. Kf = freezing point depression constant of water (-1.86°C/m) m = the molality of the solution (mol solute /kg solvent) i = the number of dissolved particles the solute produces. The i for any molecular compound is 1. dan schumacher unitedhealth group https://asoundbeginning.net
