Tüpfelreaktionen zum Nachweis von Hydroxylamin, Hydrazin und Ascorbinsäure in alkalischer Lösung

TL;DR: Ammoniakalische Losungen von Hydroxylamin, Hydrazin, and Ascorbinsaure bewirken aus ammoniakalischen Losungs von Kupfer(II)-ferrocyanid und -ferricyanid die Abscheidung von KUpfer(I)-ferricianid bzw.

Prüfung auf reduzierende organische Verbindungen mit o-Dinitrobenzol in der Tüpfelanalyse

TL;DR: Organische Verbindungen, die in alkalischer Losung als Wasserstoffdonatoren fungieren, reduzieren alkoholisch-alkalische Losungen von o- and p-Dinitrobenzol zu blauvioletten bzw. orangefarbigen wasserloslichen Alkalisalzen von chinoiden Stickstoffsauren as mentioned in this paper.
