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.
Tasks
The freezing point of a solution is lower than that of the pure solvent. The depression of the freezing point can be determined experimentally using a suitable apparatus (cryoscopy). If the cryoscopy constants of the solvent are known, the molecular mass of the subs ...
For each temperature, a specific pressure of the gas phase of the liquid establishes itself above the liquid - the vapour pressure. If the external pressure is lowered by drawing off the gas phase, the equilibrium re-establishes itself through ...
Sodium acetate trihydrate can form supersaturated solutions. Spontaneous crystallizing out of these leads to an increase in temperature. The change in temperature over time that occurs during this process can be experimentally examined.
