Activity Coefficients of Sodium Bromide at High Concentrations

Jack Penciner, Yizhak Marcus

Research output: Contribution to journalArticlepeer-review


The activity coefficients of sodium bromide in aqueous solutions at high concentrations were measured at 25.0° by the isopiestic method. Reference salt was calcium chloride. The experimental osmotic coefficients were fitted with a power series, and integrated to obtain the activity coefficients. In the region of overlapping concentrations, the osmotic and activity coefficients agree with published data.
