Abstract
The hydrolysis of the ion Ga3+ has been investigated at 60°C by potentiometric titrations in a sodium perchlorate medium of the constant ionic strength 3 m. Solutions of various total gallium concentrations B were alkalified by means of a coulometric technique. The concentrations h of the free hydrogen ions were measured with the aid of a glass electrode. From the experimental data, Z, the average number of OH bound per Ga was calculated. The mathematical analysis of the curves Z(logh)B is consistent with the following formulation of the hydrolysis reactions with log*βl = log k0 kl = −1,7 − 11,55 l.Keywords
