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.
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
That's why the boiling point of a solution is always higher than
that of the pure ...
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 ...
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 ...
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.
