Measurements of water flux, solute flux, and electrochemical potential were made simultaneously in a membrane transport system designed for the studies in anomalous osmosis and thermoosmosis using a series of cations with a common anion. The cation exchange membrane employed was dimensionally stable. The anomalous osmosis appeared to be composed of two components, the normal osmosis and a facilitated osmosis; whereas the thermoosmosis was composed solely of a facilitated component. The anomalous water flux did not correlate with the solute flux or the electro‐chemical potential. Anomalous osmosis depended strongly upon the cation species.
