Solubility of ammonia in water in the presence of atmospheric CO2.

Abstract

The equilibrium solubility of ammonia in water, in the presence of atmospheric CO2, has been determined at room temperature over the aqueous phase concentration range 75-1200 micromolar. In contrast to a previous study, we find no evidence of a deviation from Henry's Law occasioned by the presence of atmospheric CO2. We therefore conclude that the solubility of ammonia in cloud and rainwater should be adequately described by traditional solubility theory. -Authors
