• Redox Reactions


  • Define oxidation reactions and reduction reactions
  • Determine which is the reducing agent and which is the oxidizing agent
• Redox Reaction in our Daily life


  • An oxidation-reaction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction)
  • Redox reactions are all around us: the burning of fuels, corrosion of metals, and even the processes of photosynthesis and cellular respiration involves redox reaction
• Redox Reaction


  • What is a Redox Reaction?
  • Any chemical reaction in which a molecule, an atom or an ion's oxidation number is changed by gaining or losing an electron is a reduction-oxidation reaction
• Redox Reaction


  1. When electrons transfer, there should be atoms that would give away electrons, and atoms that would accept the electrons

  2. The losing of electrons or oxidation, and the gaining of electrons or reduction

  3. The substance that loses the electron is the reducing agent(RA) or the reductant and the one that accepts the electron is the oxidizing agent(OA) or the oxidant
