Proof-of-concept measurements have indicated that the surface tension of a suspended water droplet will shift when in the presence of evaporated organic compounds in the air surrounding it, with shifts that would be greater than expected of the relatively small amounts of gas that are being transferred into the droplets. This study aims to take a more systematic approach to this phenomena by exposing hanging droplets of water and ammonium sulfate solution to ethanol and isopropanol, which are both known to easily dissolve in water and can affect solution surfaces. Further work has been done conducting surface tension measurements of ammonium, sulfate, and nitrate ion solutions.
