Multiphasic profiles for the ion activities of NaBr and KBr

TL;DR

This paper demonstrates that the ion activities of NaBr and KBr exhibit multiphasic profiles with straight-line segments and discontinuous transitions, extending previous findings on similar profiles for other ions and processes.

Contribution

It introduces the observation of multiphasic ion activity profiles for NaBr and KBr, expanding the scope of such profiles beyond previously studied ions.

Findings

Multiphasic profiles observed for NaBr and KBr ion activities.

Profiles consist of straight-line segments separated by discontinuities.

Extends previous multiphasic profile findings to new bromide salts.

Abstract

The preceding paper (Nissen 2017) shows multiphasic profiles, straight lines separated by discontinuous transitions, for the ion activities of NaCl and KCl at 15, 25, 35 and 45oC based on very precise tabular data of Lee et al. (2002). In addition, references are given to previous findings of multiphasic profiles for a variety of processes and phenomena, starting with the uptake of sulfate by roots and leaf slices of barley (Nissen 1971). In a continuation, the present paper shows multiphasic profiles for the ion activities of NaBr and KBr for data also from Lee et al. (2002).
