Description

A study on the behavior of the first hydrolysis constant βEu,Hl-0 and the constant of the solubility product Kps of the europium in front of the changes of the ion force: 0. 02 M, 0.1 M, 0.7M, 2M, 3M and 4M of sodium perchlorate, at 303 K. Experimentally the potentiometry and also radioactivity measures its were used. The specific interaction of ions theory (SIT) of Bronsted-Guggenheim-Scatchard allows the extrapolation of the values to infinite dilution and the results were: log βEu,Hl-0 = -7 36 and log Kspl-0 = -24. 68. A discussion of the group of results with the data of the literature is presented. (Author)
