%X Vanadium (III) ion Hydrolysis at pH higher than 3 in KCl 3M at 25 ¡ãC. The Vanadium (III) hydrolysis has been studied at 25 oC in 3.0 M KCl as ionic medium for a range of total Vanadium concentration between 8 and 31,5 mM at pH higher than 3. The analysis of the potentiometric data by means of least-squares computational program LETAGROP, indicated the formation of the following hydroxospecies and their stability constants (-log ¦Âpq): VOH2+ (3.13 ¡À 0.08), V2(OH)24+ (3.76 ¡À 0.06), V(OH)2+ (6.86 ¡À 0.02), and V3(OH)8+ (27.47 ¡À 0.04)
