REDOX REACTIONS II
Oxidation implies LOSS of electrons  lossox
Reduction implies GAIN of electrons
• Oxidation and reduction processes always occur together.
• An oxidising agent (oxidant) accepts electrons  and is reduced in the reaction.
               eg. O2 + 4e- ® 2O2- 
• A reducing agent (reductant) supplies electrons  and is oxidised in the reaction.
              eg. H2 ® 2H+ + 2e-
