The hydrolysis equilibria of Y<SUP>3+</SUP>, La<SUP>3+</SUP>, Gd<SUP>3+</SUP>, and Er<SUP>3+</SUP> ions have been studied at 25°C in 3 M (Li)ClO<SUB>4</SUB> by measuring the hydrogen-ion concentration with a glass electrode. All the test solutions containing hydrolyzed species prepared by the addition of alkali were acidified by means of constant-current coulometry. The data, which indicate a slight hydrolysis of the relevant ions, can be explained by assuming the formation of the following complexes: Y(OH)<SUB>2</SUB><SUP>+</SUP>, logβ<SUB>2,1</SUB>=−17.0±0.1; Y<SUB>2</SUB>(OH)<SUB>2</SUB><SUP>4+</SUP>, logβ<SUB>2,2</SUB>=−14.04±0.01; LaOH<SUP>2+</SUP>, logβ<SUB>1,1</SUB>=−10.04±0.01; GdOH<SUP>2+</SUP>, logβ<SUB>1,1</SUB>=−8.20±0.01; Er(OH)<SUB>2</SUB><SUP>+</SUP>, logβ<SUB>2,1</SUB>=−17.4±0.1; Er<SUB>2</SUB>(OH)<SUB>2</SUB><SUP>4+</SUP>, logβ<SUB>2,2</SUB>=−13.72±0.01.
