The solubility of helium was measured in four aqueous alcohol solutions (methanol + water, ethanol + water, l-propanol + water, and 2-propanol+ water systems) over the full range of composition at 25 O C and 101.325 kPa. Both the excess quantity referring to the Ostwald coefficient and that referring to the excess volume show similar minima as a function of the volume fraction of alcohol.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
