Raoult's Law states that vapor pressure decreases proportionately with the number of molecules of solute dissolved in a given weight of solvent. With the materials in this kit, students follow this law as they conduct an experiment to determine the vapor pressure of a solution of water and sodium chloride.

The experiment can be completed in one hour and comes with enough materials for 15 setups.

Chemical Contents:

• Sodium Chloride

Additional Materials Required:

• Hot Plates
• Thermometers, ±0.1°C
• 1 L Beakers
• 10 mL Graduated Cylinders
• Ring Stands with Clamps
