The oxalate complexes of thorium

Abstract

(1) The ammonium, potassium and sodium salts of three complex thorium oxalates were prepared and studied. (2) Their solubilities and conditions of stability were studied. (3) The reaction between thorium and excess oxalate, and vice versa, was studied by means of conductivity and high frequency conductivity measurements. (4) The formation constant of Th(C₂O₄)₄⠴⠻ and Th(C₂O₄)₃²⠻, and the solubility product of (NH₄)₂Th₂(C₂O₄)₅, were determined by a solubility method.
