Direct quantification of changes in pH within single levitated microdroplets and the kinetics of nitrate and chloride depletion
Kyle J. Angle, Vicki H. Grassian
Abstract
Glycine is used as an in situ probe of the kinetics of changes in aqueous microdroplet pH as chloride and nitrate deplete within the microdroplet due to the protonated strong acid forming at the air/water interface and partitioning into the gas phase.
