Can a different chemical, change the boiling point of H2O? My hypothesis is that the reaction is based on the chemicals used on this experiment.
Question Date: 2004-04-06
Answer 1:

Yes, for example, if you dissolve salt in water, the boiling point goes up in a few degrees. This is because you now have a solution of two components and before the water molecules can evaporate they need to separate from the salt. This requires more energy. If you have a small amount of salt the increase of the boiling point is very little because most of the water molecules do not see the salt. As you add more salt a larger number of water molecules need to separate from the salt and the boiling point increases accordingly.
