Vapor Pressures and Osmotic Coefficients of Aqueous Solutions of SDS, C6TAB, and C8TAB at 25 °C

“…Figure shows the well-known pattern of the osmotic coefficient for highly associating electrolytes (cf. osmotic coefficients of electrolytes in nonaqueous solvents − ). The sharp decrease of the osmotic coefficients is due to the formation of micelles, which takes place at 25 °C at about 0.008 mol/kg. − The concentration range below the cmc is not accessible in this study.…”

“…This pressure difference may have its origin in small amounts of remaining permanent gas or in temperature fluctuations in the order of 0.0001 °C. For details of the measuring and operating procedures, see ref .…”

Experimental and theoretical studies of thermodynamics of lithium halide solutions – ethanol mixtures

“…A number of different methods for measuring the vapor pressure of electrolyte solutions have been considered for their reliability, simplicity, and quickness of the measurements [12][13][14][15][16][17][18]. The isopiestic [6] and vapor pressure lowering [18] methods generally are the most vastly used ones by which the osmotic coefficient (/) of electrolyte solution is measured and used to calculate the activity of electrolyte solutions:…”

Isobaric vapour–liquid equilibria of binary 1-propoxy-2-propanol mixtures with water and alcohols at reduced pressure

“…The differential-pressure measurement apparatus used in this work is based in principle on the highly precise measuring system built in our institute several years ago [17]. Its construction, setup, operation and calibration is explained in detail elsewhere [18].…”

“…Herein the pure ensemble of compound i embedded in the conductor is the reference state, expressed by 0 i in Eq. (17). A COSMO calculation gives the polarization charge density of the conductor resulting from the screening of the solute electric field and is usually carried out at an adequate quantum level as provided by density functional theory (DFT).…”
