Polarography of inorganic substances in anhydrous sulpholan

Abstract

Polarographic and voltammetric results are reported for 22 inorganic substances in anhydrous sulpholan with 0·1M-perchlorates as base electrolytes and a reference electrode of silver–silver chloride–saturated tetraethylammonium chloride in sulpholan. The redox behaviour of these substances and their positions in the polarographic series are similar in sulpholan and aqueous solutions, with the interesting exceptions of bromide, oxygen, and certain of the rare-earth ions.
