Document Summary
Colligative properties of solutions are defined as those properties that depend on. Introduction: the concentration of the particles in the solution rather than the nature of the particles. If a solute is added to a solvent, the freezing point temperature of the solution lowers, which is relative only to the solvent. The purpose of this lab is to prepare a solution with an unknown solute and. The following experiment involves the use of acetone (via the thermometer), naphthalene as a solvent and measure the change is the freezing point . Based on the change in freezing point and the freezing point constant (kf=6. 9 c/molal) for naphthalene, we will then be able to calculate the molality, and thus the molecular weight of the unknown solute. It is important to be aware that the freezing point of a pure substance is accurately determined by the temperature/time data for the cooling of the substance when it is melted.
