Description / Table of Contents:
Fluoroberyllate und saure Fluoroberyllate des dreiwertigen Chroms konnten dargestellt werden, sie sind den entsprechenden Alaunen ähnlich. Diese Fluoroberyllate sind violett gefärbt, es bilden sich jedoch rasch, vor allem bei erhöhter Temperatur, grün gefärbte Komplexe. Entsprechende Verbindungen des Aluminiums oder Eisens konnten nicht dargestellt werden, da diese Ionen sehr beständige komplexe Fluoride bilden.
Notes:
The present investigation has been successful in the preparation of trivalent complex chromic fluoberyllate. The preparation and properties of an acid chromic fluoberyllate alum and its dehydrated product acid chromic fluoberyllate dihydrate together with a violet rubidium chromium alum, analogous to corresponding sulphate compounds have been studied. The main difficulty encountered in the preparation of fluoberyllates of other trivalent elements was due to unique stability of the complex fluorides of the said trivalent metals. The fluoberyllate alums of the chromium are violet in colour, but it rapidly changes to green with time and also with the increase in temperature.
