    Description / Table of Contents: Zusammenfassung Cu2+, Ni2+, Cr3+, Bi3+, ZrO2+, Th4+, Pb2+ und Al3+ wurden bestimmt, indem man einen Überschuß an ÄDTA-Lösung zugab und mit Eisen(III)-chloridlösung zurücktitrierte. Als Indicator wurde 1-Hydroxy-2-naphthoesäure oder 2-Hydroxy-3-naphthoesäure verwendet. Es wurden gute Ergebnisse erzielt.
    Notes: Summary Cu2+, Ni2+, Cr3+, Bi3+, ZrO2+, Th4+, Pb2+ and Al3+ have been determined by adding an excess of EDTA solution and back titrating with ferric chloride solution, using 1-hydroxy-2-naphthoic or 2-hydroxy-3-naphthoic acid as indicator. Good results have been obtained.

    Description / Table of Contents: Zusammensetzung und Stabilität der aus Fe37+ und o-Kresotinsäure gebildeten blauvioletten Chelatverbindung wurden spektrophotometrisch bei αDmax = 550 mμ ermittelt. Es ist ein 1 : 1-Komplex, für dessen Beständigkeitskonstante bei 35,5°C und pH 1,93; 2,90 und 3,92 folgende Werte erhalten wurden: log k = 4,61; 4,15 bzw. 3,40.
    Notes: The formation of a bluish violet chelate between iron(III) and o-cresotic acid with absorption maximum at 550 mμ has been observed. The composition of the chelate has been determined spectrophotometrically using methods of continuous variation, slope ratio and mole-ratio; the ratio of iron(III) to o-cresotate corresponded to 1 : 1. These data were further utilised for the computation of stability constant (log k) at pH 1.93, 2.90 and 3.92, which at 35.5°C worked out to be 4.61, 4.15 and 3.40 respectively.
