Data compilation copyright by the U.S. Secretary of Commerce on behalf of the U.S.A. All rights reserved.

Data compiled by: Rolf Sander

Henry's Law constant (water solution)

kH(T) = H exp(d(ln(kH))/d(1/T) ((1/T) - 1/(298.15 K)))
H = Henry's law constant for solubility in water at 298.15 K (mol/kg*bar)
d(ln(kH))/d(1/T) = Temperature dependence constant (K)

H (mol/kg*bar) d(ln(kH))/d(1/T) (K) Method Reference Comment
0.00019 QN/A missing citation give several references for the Henry's law constants but don't assign them to specific species.
