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 .
