Microchimica Acta Aims and scope Submit manuscript

Summary

Cobalt (III) acetate prepared in glacial acetic acid has been utilized for the potentiometric titration of molybdenum(V) from 45.85 mg to 334 μg with a maximum relative standard deviation of 0.71% and 0.01% respectively in5N HCl. The method is convenient and rapid. There is no interference by Ni(II), Mn(II) and Cr(III) within the limits prescribed.

Zusammenfassung

In Eisessig hergestelltes Kobalt(III)acetat wurde zur potentiometrischen Titration von Molybdän(V) verwendet. Im Bereich zwischen 45,85 mg und 334 μg beträgt die relative Standardabweichung in 5-n Salzsäure 0,71% bzw. 0,01%. Ni(II), Mn(II) und Cr(III) stören innerhalb der vorgeschriebenen Grenzen nicht.
