Abstract
The chelation reaction between Cu (II) and fulvic acid has been investigated using a relatively new direct approach — that of titration with a cupric ion-selective electrode. The results of different investigators are in fair agreement with each other if they are interpreted in terms of both pH and mole fraction of reactants. In 0.1 M sodium nitrate solutions with a copper mole fraction equal to 0.5 ± 0.2, the equilibrium quotient at 25 C and pH 3 was found to be 2.2 ± 0.1.
