The possibility of using acid-alkali solutions to precipitate rubidium in the form of its hexachlorotelluride

The possibility of isolating rubidium from acid-alcohol solutions in the form of its complex halogenide with tellurium is considered. The solubility of potassium, sodium, and rubidium in solutions of the mixture of hydrochloric acid and ethanol with their various volume ratios at t = 25°C is investi...

Description
Summary:The possibility of isolating rubidium from acid-alcohol solutions in the form of its complex halogenide with tellurium is considered. The solubility of potassium, sodium, and rubidium in solutions of the mixture of hydrochloric acid and ethanol with their various volume ratios at t = 25°C is investigated. The possibility of increasing the degree of isolation of Rb in the form of its hexachlorotellurite (Rb 2 TeCl 6 ) upon going from acidic to acid-alcohol solutions is shown.
