Physical Chemistry

1. Oxidation, Reduction and Redox Reactions

   • Redox = OILRIG
     • Oxidation Is Loss, Reduction Is Gain (of electrons)
   • REDUCING AGENT: electron donor
   • OXIDISING AGENT: electron accepter
   • The oxidation state is the number of electrons lost or gained by an atom in a compound
     • Oxygen= -2
       • Peroxides= -1
       • In OF2= +2
     • Hydrogen= +!
       • Metal hydrides = -1
     • Aluminium= +3
     • Fluorine= -1
     • Chlorine= -1
       • Compounds with F&O = +values
     • All group 1 elements = +1
     • All group 2 elements = +2
