This law only holds for ideal binary mixtures, with positive or negative deviations occuring depending on whether the activity coefficient is greater than one or less than one.
Solutions are called perfect is they obey this law over a wide range of concentrations. This law only holds for ideal binary mixtures, with positive or negative deviations occuring depending on whether the activity coefficient is greater than one or less than one. These deviations for mixtures of liquids result in the formation of azeotropes. Stated mathematically as p equals p sub 0 times X, FTP, what is this chemical law stating that the partial pressure of a solvent is proportional to its mole fraction?
