Activity coefficients for aqueous solutions of potassium succinate (K2Succ) at 25 °C

Abstract

Activity coefficients for aqueous potassium succinate solutions (K₂Succ) have been determined at 25 °C from the e.m.f. measurements of cells: ISE-K | K₂Succ (m)| Hg₂ Succ|Hg. The results obtained were analysed by using various theoretical equations (extended Debye–Hückel, Pitzer etc.) and compared with those reported in a previous paper for the sodium salt.
