Answer:A disproportionation reaction is a redox reaction in which one species undergoes BOTH oxidation and reduction.Explanation:This is best illustrated by an actual example. Chlorine gas is known to undergo disproportionation in alkaline conditions to give chloride and chlorate ions.Reduction12Cl2(g)+e−→Cl− (i)Oxidation12Cl2(g)+6HO−→ClO−3+5e−+3H2O (ii)And 5×(i)+(ii) gives:3Cl2(g)+6HO−→5Cl−+ClO−3+3H2OWhich is balanced with respect to mass and charge, as is always required. Clearly zerovalent chlorine gas has undergone reduction to chloride ion, and oxidation to chlorate ion; i.e. a disproportionation reaction.
