Boiling Point Elevation 4-4 Boiling Point Elevation If you dissolve a substance such as ordinary table salt (NaCl) in water‚ the boiling point of the water will increase relative to the boiling point of the pure water. In this assignment‚ you will dissolve a sample of NaCl in water and then measure the boiling point elevation for the solution. 1. Start Virtual ChemLab and select Boiling Point Elevation from the list of assignments. The lab will open in the Calorimetry laboratory with a calorimeter
