On the Formation of Complex Ions Applied in Analytical Chemistry. VIII : Studies on Complexbilities of Ferric Compounds by the Use of Radioisotope Element

application/pdfApplying the ion exchange method reported by J. Schubert, the complexbilities of ferric tartrate, citrate and malonate were measured by the use of the radioisotope element of Fe^ and the ion exchange resin of Amberlite 1R-120. The hydrogen ion concentrations of the solution were measured by the use of the quinhydrone electrode. All the measurements were made at 25℃ and the following results were obtained : ferric tartrate, K=3.1×10^ citrate, K=2.2×10^ ; malonate, K=2.5×10^.紀要類(bulletin)309141 bytesdepartmental bulletin pape
