Notes: (1) The solubility form of Henry’s constant may be calculated as: H (mg i=LH 2 O)=atm i) ¼ Ae B (T C) (H.60) taking A and B from the table for the
i
gas of interest.
(2) All columns except O 3 and Rn were from Dean, J. A. (Ed.), Lange’s Handbook of Chemistry, 13th edn., McGraw-Hill, New York, 1985.
