A reassessment of rhodizonic acid as a qualitative reagent

Summary

Rhodizonic acid has been re-examined as a qualitative reagent, and it has been shown that it will react with many metals to give characteristic spectra if the dielectric constant of the solvent is sufficiently low and if a protective colloid is added. The range of application of rhodizonic acid has been considerably extended in this way.

Zusammenfassung

Rhodizonsäure wurde als qualitatives Reagens überprüft. Sie reagiert mit vielen Metallen und gibt charakteristische Spektren, wenn die Dielektrizitätskonstante des Lösungsmittels klein ist und man ein Schutzkolloid zusetzt. Das Anwendungsgebiet der Rhodizonsäure wurde damit erheblich vergrößert.
