    reduction (electron gain).
  2. The oxidizing agent is-----------, and the reducing agent is ----------------
    • reduced
    • oxidized.
  3. The number of electrons gained by the oxidizing agent always equals
    the number lost by the reducing agent.
  4. Reduction occurs at the ------------
    cathode
  5. Oxidation occurs at the --------
    anode
  6. ---------------> 0 for a spontaneous reaction
    Ecell
  7. 1 Volt (V) =
    1 Joule (J)/ Coulomb (C)
  8. 1 coulomg (C)=   --------------
    1 Joule (J)/1Volt (V)
  9. electrode potentials are written as
    reductions ie zinc =-1.76 but if you want to use it for oxidation reverse sign to +1.76
