A species is oxidized during a redox reaction. What has happened to it?
AIt has gained electrons
BIt has gained protons
CIt has lost protons
DIt has lost electrons
Answer & Solution
Correct answer: D. It has lost electrons
1. Oxidation and reduction are defined by the movement of electrons.
2. Oxidation is the loss of electrons, so the oxidized species gives electrons away.
3. Reduction is the opposite, a gain of electrons.
4. Protons sit in the nucleus and do not move during a redox reaction.
