Define the oxidation and reduction reaction with example |
|
Answer» Oxidation means the gain of oxygen and loss of hydrogen. Reduction means the loss of oxygen and gain of hudrogen A reaction in which one reactant undergoes oxidation whereas the other gets reduced during the course of reaction are termed as oxidation-reduction reactions or redox reactions. Oxidation refers to the loss of electrons or increase in oxidation state by a molecule, atom, or ion. Reduction refers to the gain of electrons or decrease in oxidation state by a molecule, atom, or ion.Consider the following redox reaction.\tBurning sugars, such as glucose (C6H12O6) and the fatty acids in the fats we eat.\tC6H12O6(aq) + 6 O2(g) --> 6 CO2(g) + 6 H2O(l)\t\tReaction of zinc oxide and carbon.ZnO + C --> Zn + COIn this reaction carbon is oxidised to CO and ZnO is reduced to Zn.
