Polarography of inorganic compounds in acetic acid–acetic anhydride solution

Abstract

Polarographic data for 23 inorganic species in acetic acid–acetic anhydride (20:1, v/v) are reported, the base electrolytes being 0·25M-sodium perchlorate, 0·25M-sodium acetate, and 0·25M-lithium chloride. Evidence is presented to show that inorganic ions are solvated less readily in the organic solvent than in aqueous solution, but the order of reduction of ions is similar to that for aqueous solutions, with the exception of nickel, which is reduced much more readily in the non-aqueous solvent. Both acetate and chloride ions are moderately good complexing agents for inorganic ions in the organic solvent.
