1. Effects of Hofmeister anions on DPPC Langmuir monolayers at the air-water interface

Abstract

The effect of sodium salts of different monovalent anions belonging to the Hofmeister series on Langmuir monolayers of DPPC is presented. The findings reveal that anions partition into or bind to the looser liquid-expanded phase, thus providing entropic stabilization of that phase, but do not penetrate into or bind to the domains of the liquid-condensed phase.

2. Simultaneous determination of the ionization constant and the solubility of sparingly soluble drug substances: a physical chemistry experiment

Author

Aroti, Andrea and Leontidis, Epameinondas

Subjects
Chemistry, Physical and theoretical -- Study and teaching, Ionization constants -- Study and teaching, Potentiometry -- Study and teaching, Spectrophotometry -- Study and teaching, Dibucaine -- Analysis, Chemistry, Education, Science and technology
Abstract

A physical chemistry experiment using dibucaine has been developed for teaching students about simultaneous determination of the ionization constant and the solubility of sparingly soluble drug substances. They use the inverse titration method with dissolution of a precipitate and gain experience with potentiometry and spectrophotometry.
