From: Hygroscopic behavior and aerosol chemistry of atmospheric particles containing organic acids and inorganic salts

Fig. 10

Panels (left), (middle) and (right) show the temporal evolution of reaction extents, ϵ(t), for the chloride, nitrate, and ammonium depletion, respectively, in aerosol microdroplets with a radius of 1 μm at 90% RH. The inorganics and organics in aerosols are mixed in a stoichiometric ratio. The style of the black curves indicates the type of dicarboxylic acids (H2A) or the corresponding disodium salts (Na2A) involved in the depletion reactions–oxalic acid (OA) or oxalate (dotted curves), malonic acid (MA) or malonate (dashed-dotted curves), succinic acid (SA) or succinate (dashed curves) and glutaric acid (GA) or glutarate (solid curve).
