Preferred Label : Henry's law;
IUPAC definition : The partial pressure (fugacity) of a solute (B) in a solution is directly proportional
to the rational chemical activity (ax) of the solute; this relationship is called
Henry's law: \[p_{{B}} \frac{a_{x,{B}}}{\alpha _{x,{B}} {\infty }}\] where a x,B is
the rational solubility coefficient for infinite dilution, i.e. for pure solvent.
For the solvent (A) the relationship is called Raoult's law, and the proportionality
factor is the fugacity of the pure solvent, p( )A : \[p_{{A}} \overset{ }{p}_{{A}}
{\ast }\ a_{{A}}\];
