Radiochemische Messung der Löslichkeit von Silberhalogeniden in Wasser und in Natriumhalogenidlösungen und die Komplexbildung der Silberhalogenide mit Halogenionen

Abstract: InhaltsubersichtDie Loslichkeit der Silberhalogenide AgCl, AgBr und AgJ bei 18" C in Wasser uud in Natriumhalogenidlosungen bis zu Konzentrationen von 2 Mol/Liter aufwarts wurde radiochemisch bestimmt. Die Versuche wurden mit gefallten und gealterten Silberhalogenidprapafaten durchgefuhrt, die mit 1l"Ag bzw. 111Ag markiert waren. Der EinfluB der Aktivitatskoeffizienten auf die Loslichkeit der Silberhalogenide wird diskutiert. Die rechnerische Analyse der Loslichkeitskurven ergibt : Alle Silberhalogenide liege… Show more

“…In aqueous solutions, silver cations also form complexes with halide ions, AgX n (n-1)with n ) 1-4, depending on the [Ag + ]/ [X -] ratio. 34 In our experimental conditions, the (AgBr 2 -, CTA + ) complex is probably the predominant complex. 35 Because of their steric hindrance, this complex and (Au III Br 4 -, CTA + ) are probably localized on the micelle caps.…”

“…Consequently, many investigations are devoted to the problems of solubility and leaching, respectively [3,[6][7][8][9][10][11]. It should also be mentioned that even for pure and well-defined compounds, like SrS0 4 , PbS0 4 or Agl, solubility is only in a restricted range given by the solubility product and solubility of neutral particles and of complexes has to be taken into account [12][13][14][15][16][17]. Furthermore, in case of solid solutions (mixed crystals) the solubility of the components is different from that of the pure compounds [18,19].…”

“…To remove interfering Ag + , NaBr is dissolved in the analyte solution. , The presence of 0.1 M Br – precipitates AgBr and lowers the solubility of AgBr to ∼10 –6 M, ensuring that no measurable Ag + is free to migrate to and be reduced by the working electrode. Thus, a carbon working electrode (cathode) and silver counter electrode (anode) in a single cell may be constructed for fast, facile, and quantitative coulometric titration of acid.…”
