The behaviour of sodium deoxycholate aqueous solutions at 25°C, using different concentrations of N(CH3)4Cl as the ionic medium, was studied. Electromotive force measurements of galvanic cells containing electrodes reversible to sodium deoxycholate (DC) and hydrogen ions were performed. Moreover, the influence of sodium and DC ions on the solubility of lead (II) deoxycholate was investigated. Experimental data were explained by assuming the formation of several species of the type Na q H p (DC) n . The general trend is that theq, p, n values increase with increasing concentration of N(CH3)4Cl. The observed aggregation numbers of the largest micellar aggregates satisfactorily agree with those obtained by small-angle X-ray scattering measurements.

Abstract
The behaviour of sodium deoxycholate aqueous solutions at 25°C, using different concentrations of N(CH3)4Cl as the ionic medium, was studied. Electromotive force measurements of galvanic cells containing electrodes reversible to sodium deoxycholate (DC) and hydrogen ions were performed. Moreover, the influence of sodium and DC ions on the solubility of lead (II) deoxycholate was investigated. Experimental data were explained by assuming the formation of several species of the type Na q H p (DC) n . The general trend is that theq, p, n values increase with increasing concentration of N(CH3)4Cl. The observed aggregation numbers of the largest micellar aggregates satisfactorily agree with those obtained by small-angle X-ray scattering measurements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
