Q
What 2 factors affect size of redox potential?
A
1) ligands
2) pH
2
Q
How does the type of ligand affect the size of redox potential?
A
Different ligands may affect the size of the redox potential depending on how well the ligands bind to the metal ion in a particular oxidation state.
3
Q
How does pH affect size of redox potential?
A
Redox potentials are usually larger in lower pH ( more acidic solutions).
- A larger redox potential, means that the ion is more easy to reduce.
