Hydroxide complexes of lanthanides-III Gadolinium(III) in perchlorate medium.
From the precipitation borderline in the pM'-pH diagram, determined experimentally under CO(2)-free conditions, the stability constants of the mononuclear and polynuclear species of gadolinium hydroxide have been established. The values found are log*beta(1) = -7.3, log*beta(2) = -14.6, log*beta(3) = -21.9, log*beta(4,3) = -19.0 and log *K(s)(0) = 17.0. They refer to fresh precipitates, prepared at room temperature in sodium perchlorate medium with an ionic strength of 1.
