Abstract
Solubilities and surface tensions were measured for difunctional organ ic acids in various concentrations of (NH4)(2)SO4 and NH4HSO4 aqueous solutions. Model results using these data indicate that the organic co mpounds affect cloud droplet growth by two mechanisms: by gradual diss olution in the growing droplet which affects the shape of the Kohler g rowth curve, and by lowering of surface tension which decreases the cr itical supersaturation.
