On the Complex Chemistry of the Tervalent Rare Earth Ions. II. The Acetate Systems of Praseodymium, Samarium, Dysprosium, Holmium, Erbium, and Ytterbium.

Six rare earth acetate systems were examined potentiometrically and one extinctiometrically. The complexity and stability constants are listed. All measurements were performed in perchlorate medium of ionic strength 2 M at 20 C. The extinctiometnic investigation of the Er/sup 3+/-Ac/sup -/ system shows that the rormation of the acetate complexes is accompanied by the appearance of new peaks close…
