Costa Rica Wagon Wheel - Summarizing. Overall, the colligative properties can be very useful in our everyday lives. The neat thing about them is that it doesn't matter what the solute is, just how much is there. For example, if you added the same number of moles of sugar and salt, the salt would have a greater effect than the sugar because it is ionic. The reason ethylene glycol has such a large effect on the . Background: Colligative properties are properties of a solvent, such as freezing point depression and boiling point elevation, which depend on the concentration of solute particles dissolved in the solvent. The decrease in freezing point, ΔTf (freezing point depression) for a near ideal solution can be described by the equation: ΔTf = kf · m Eq 1. The normal freezing point of t-butyl alcohol is around degrees Celsius while that of pure water is degrees Celsius. As seen in table 3, the freezing point of the substance was lowered degrees when water was added to the mix. This illustrates the intensity of colligative properties among different solutes and solvents.5/5(12). The Presidency and Democracy
