WebJul 19, 2024 · The freezing point is the temperature at which the liquid changes to a solid. At a given temperature, if a substance is added to a solvent (such as water), the solute-solvent interactions prevent the solvent from going into the solid phase. 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. teladan tokoh alkitab
