3. Effect of competing reactions of complex formation on the potential of redox systems. I-, CN-, SCN- form complex compounds with Cu that are more stable than with Cu2. How does this affect the iodometric determination of Cu2? The presence of which ligand has the greatest effect. E0 (Cu2 / Cu) \u003d 0.15V. logβ (CuI2-)=8.85 logβ (Cu(CN)2-)=24.00 logβ (Cu(SCN)2-)=12.11
