Oxidation and Reduction

Another name for a "oxidation-reduction" reaction is

• chemical reaction

• neutralization reaction

• redox reaction

• nuclear reaction

In a redox reaction, the species reduced

• gains electrons and is the oxidizing agent

• loses electrons and is the oxidizing agent

• loses electrons and is the reducing agent

• gains electrons and is the reducing agent

If an atom loses electrons during a chemical reaction, the atom was:

• Oxidized

• Reduced

• Neutralized

• Precipitated
