Principle
The boiling point of a solution is always higher than that of
the pure solvent. The dependence of the temperature difference
(elevated boiling point) on the concentration of the solute can be
determined using a suitable apparatus.
Benefits
- Simple presentation and execution by temperature meter 4-2
- Simultaneous display of current temperature and temperature difference
- Compact, easily transportable setup
Tasks
- Measure the increase in the boiling point of water as a
function of the concentration of table salt, urea and
hydroquinone.
- Investigate the relationship between the increase in boiling
point and the number of pellets.
- Determine the molar mass of the solute from the relationship
between the increase in boiling point and the concentration.
