HENRY’S LAW<br />
� P i = H.X i or X i = (Y i / H).P<br />
� This implies that <strong>ac</strong><strong>id</strong> gas absorbed in liqu<strong>id</strong><br />
phase (X i) is proportional to its gas mole fr<strong>ac</strong>tion (Y i)<br />
and inversely to Henry’s constant (which is constant<br />
for a given temperature).<br />
� Much more importantly, the solubility is proportional<br />
to the total gas pressure (P).<br />
� This means that at high pressure, <strong>ac</strong><strong>id</strong> gases will<br />
dissolve in solvents, and as the pressure is released,<br />
the solvent can be regenerated.
