The uptake of oxygen by aqueous solutions containing cobalt(II) ions and ethylenediamine
Abstract
The amount of oxygen taken up by aqueous solutions of various cobalt(II) salts containing ethylenediamine (en) attains a maximum for a stoicheiometric Co : en ratio of 1 : 3. In the products, isolated from the reaction mixture by the addition of alcohol, the Co : en ratio varies from 1 : 1·5 to 1 : 2·75.
