Abstract

The enthalpies of dilution of solutions of two bile salts in water and aqueous NaCI were measured over a range of solute concentrations encornpassing the critical micellization concentrations (c.m.c.). The compounds were sodium taurodeoxycholate and sodium taurochoiate. An isoperibolic reaction calorimeter was used. The observed changes of enthalpies of dilution as a function of surfactant and NaCI concentrations were related to the c.m.c.values, micellar aggregation numbers and counterion binding.
