Abstract

A comparison is given between the osmotic coeffs. inferred from direct vapor pressure lowering and from indirect vapor pressure osmometry, for three aq. surfactant solns. at 25 °C. The results show that vapor pressure osmometry is a rapid but very reliable technique even at room temp., in contrast to the indications of the manufacturer. Furthermore, the comparison of both techniques reveals that dissolved gas has no noticeable influence on the osmotic coeffs.
