VANADIUM(III) COMPLEXES IN AQUEOUS SOLUTION WITH THE DICARBOXYLIC OXALIC, MALONIC AND SUCCINIC ACIDS
The complex species formed in aqueous solution (25 °C, I = 3.0 mol.dm-3 KCl ionic medium) between V3+ cation and the dicarboxylic acids oxalic, malonic and succinic (H2L) have been studied potentiometrically. The application of the least-squares computer program LETAGROP to the experimental (emf H)...
