The Role of Oxidation States in Redox Titrations
Quick fact
In redox titrations, the oxidation state changes at the equivalence point by exactly the number of electrons transferred, allowing the calculation of unknown concentrations from the volume of titrant used.
Why this is interesting
Imagine you’re a chemist trying to determine the exact amount of iron in a sample. You add a chemical that changes color, and suddenly you know the answer—but only if you can track every electron. How does a simple number assigned to each atom make this possible?
