Boiling point elevation - Raoult's law with Cobra4

Principle

Raoult's law states: The vapour pressure of an ideal solution is directly dependent on the vapour pressure of each chemical component and the mole fraction of the component present in the solution.
That's why the boiling point of a solution is always higher than that of the pure ...

Melting-point lowering and boiling-point elevation

Principle

Solutions have a higher boiling point and a lower melting point than the pure solvent. The shift of the melting and boiling point is based on the interaction between solvent particles and the dissolved substance. In this experiment the melting and boiling point of different ...
