        REDOX REACTION
  • Chemical reactions which involves both 
   oxidation as well as reduction process 
   simultaneously, are known as redox reactions 
   (‘red’) from reduction and ‘ox’ from oxidation)
  •  All these reactions are always accompanied 
   by energy change in the form of heat, light or 
   electricity
                    REDUCTANTS AND OXIDANTS
      •  Oxidant or oxidising agent is a chemical substance which can 
         accept one or more electrons and causes oxidation of some 
         other species. In other words, the oxidation number of 
         oxidant decreases in a redox reaction
      •  Important Oxidants
         Molecules of most electronegative elements such as O , O , 
                                                                        2   3
         halogens.
         Compounds having element in its highest oxidation state e.g.,
         K Cr O , KMnO , HCIO , H SO , KCIO , Ce(SO ) ,

         Oxides of metals and non-metals such as MgO, CrO , CO , etc.
                                                                    3     2
        REDUCTANT OR REDUCING AGENT
    • Reductant or reducing agent is a chemical 
      substance which can give one or more electrons 
      and causes reduction of some other species. In 
      other words, the oxidation number of reductant 
      increases in a redox reaction.
    • Important Reductants
      All metals such as Na, AI, Zn, etc., and some non 
      – metals, e.g., C, S. P, H , etc.
                          2
      Metallic hydrides like NaH, LiH. KH, CaH  etc.
