Section 1 Ideal and Real Solutions
ΒΆSubsection 1.1 Defining the Ideal Solution
As we've seen, the vapor pressure of a liquid is related to the strength of molecular interactions. In an ideal multicomponent solution, all substances have equally strong chemical interactions. The vapor pressure \(P_i\) of some component \(i\) in equilibrium with the solution is thus given by $$P_i=x_iP_i^*$$.
