Gas-liquid reactions occur widely in our lives, including processes in atmospheric aerosols, the commercial production of sulfuric acid, and gas transport at the air/lung interface. We have continually refined our molecular view of these interfacial interactions as new computational and experimental tools have become available. In this talk, I will describe gas-liquid scattering experiments between gaseous acids such HCI and protic solvents such as salty glycerol and salty water. These studies lead to a detailed picture of the ways in which impinging gas molecular bounce off, react, and dissolve in liquids. In particular, we identify an ultrafast DCI-HCI proton exchange at the surface of glycerol that is catalyzed by alkali halide salts. We have recently begun searching for this interfacial exchange reaction in cold salty water.
