Studies on the Synthesis of Metal Complexes. II. Synthesis and Absorption Spectra of Hydrogen Ethylenediaminetetraacetato-cobaltate (III) and Sodium-hydrogen Chloro-ethylenediaminetetraacetato-cobaltate(III)

Abstract
Two new compounds, H[Coedta]·4H2O and Na[Co(Cl) (edtaH)]·2H2O were synthesized, and their chemical formulae were confirmed by means of potentiometric titration and by examination of the infrared spectrum.
