enthalPy of hydration of Gases
The molar enthalpy of hydration Δ
hyd
H
∞
is defined as the en-
thalpy change when one mole of an ideal gas is dissolved in an in-
finite amount of water . Another term for this quantity is enthalpy
(heat) of solvation in water at infinite dilution . The enthalpy of
hydration influences the distribution of a volatile compound be-
tween the aqueous solution phase and air and is thus important in
fields such as environmental science, geochemistry, and chemical
engineering . It is related to the enthalpy of solution of the liquid or
solid phase, Δ
sol
H
∞
, by
Δ
hyd
H
∞
= Δ
sol
H
∞
– Δ
vap
H
0
where Δ
vap
H
0
is the molar enthalpy of vaporization . This table
gives the molar enthalpy of hydration for a number of common
substances .
