A summary of colligative properties in 's colligative properties of solutions learn exactly what happened in this chapter, scene, or section of colligative properties of solutions and what it means. Very few of the physical properties of a solution are colligative properties because the change in vapor pressure is a colligative property. Cognitive properties ashley weber principles of chemistry 2 experiment 1 02/02/2015 abstract: several experiments were performed to observe the colligative properties. In this experiment, the objective was to observe the effects of some of the colligative properties of solutions the freezing points of distilled water and saltwater were measured, and found to both be about 0 °c. Chem-i #12: in the preliminary activity, you will gain additional experience using a temperature probe as you determine the boiling point of water after completing the preliminary activity, you will first use reference sources to find out more about the colligative properties of solutions before you choose and investigate a researchable.
Experiment 1: colligative properties determination of the molar mass of a compound by freezing point depression objective: the objective of this experiment is to determine the molar mass of an unknown solute by measuring the freezing point depression of a solution of this solute in a solvent as compared to the.
