1. Oxidation and Reduction

Key Concepts & Definitions

  • Oxidation: The loss of electrons by a substance during a chemical reaction. It increases the oxidation state of an element.
  • Reduction: The gain of electrons by a substance during a chemical reaction. It decreases the oxidation state of an element.
  • Oxidizing Agent: A substance that accepts electrons and causes another substance to be oxidized.
  • Reducing Agent: A substance that donates electrons and causes another substance to be reduced.
  • Redox Reaction: A chemical process involving simultaneous oxidation and reduction, where electrons are transferred from one species to another.
  • Oxidation State: A number assigned to an element in a compound representing the number of electrons lost or gained relative to its elemental form.
