The form of raoult's law is modified to express the activity of water a(h2o) for aqueous electrolyte solutions by the mole fraction of a free (nonsolvating) solvent structural unit raised to the reciprocal power of the solvent structural constant. For a solution of two liquids, a and b, raoult's law predicts that if no other gases are present, then the total vapor. Raoult's law for …

Jump to navigation Jump to search. Raoult's law (/ˈrɑːuːlz/ law) is a law of thermodynamics established by French chemist François-Marie Raoult in 1887. It states that the partial vapor pressure of each component of an ideal mixture of liquids is equal to the vapour pressure of the pure component multiplied by its mole fraction in the mixture.

Non-ideal mixing. In elementary applications, Raoult's law is generally valid when the liquid phase is either nearly pure or a mixture of similar substances. Raoult's law may be adapted to non-ideal solutions by incorporating two factors that account for the interactions between molecules of different substances.

If deviations from the ideal are not too large, Raoult's law is still valid in a narrow concentration range when approaching x = 1 for the majority phase (the solvent). The solute also shows a linear limiting law, but with a different coefficient. This law is known as Henry's law.

Proposed by French chemist François-Marie Raoult in 1887, it states that the partial pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component multiplied by its mole fraction in the mixture.
