However, in a binary
liquid solution, if both the components of the solution are volatile then another
form of Raoult’s law is used Mathematically, this form of the Raoult’s law is stated
as:

p x Solutions which obey Raoult’s law over the entire range
of concentration are called ideal solutions Two types of deviations from Raoult’s
law, called positive and negative deviations are observed
