Elevación del punto de ebullición


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.


  1. Measure the increase in the boiling ...

Boiling point elevation - Raoult's law with Cobra4


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 ...

Depresión del punto de congelación


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 substance ...

Equilibrio de evaporación


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 evaporation of parts of the ...

Diagrama de fusión de un sistema binario con Cobra4


In plotting the cooling curves of binary mixtures one determines the temperatures of melting and solidification of specimens with differing fractions (molar fractions) of the two components. These results are entered in a temperature versus ...

Model experiments of hand warmers (Principle of latent heat storage tanks)


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.
