REDOX REACTIONS (MNEMONICS):FAT CAT and OX mnemonics for oxidation reaction
2 minute read
Oxidation- Reduction reaction
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.
1.Burning sugars, such as glucose (C6H12O6) and the fatty acids in the fats we eat.
C6H12O6(aq) + 6 O2(g) --> 6 CO2(g) + 6 H2O(l)
2.Reaction of Manganese dioxide with hydrochloric acid involves redox reaction.
Reaction of zinc oxide and carbon.
ZnO + C --> Zn + CO
In this reaction carbon is oxidised to CO and ZnO is reduced to Zn.
Balancing Redox Equations
Key Points
1.Reducing agents get oxidized, and therefore lose electrons.
2.Oxidizing agents get reduced, and therefore gain electrons.
3.Remember the mnemonic device OIL RIG—”Oxidation Involves Loss” and “Reduction Involves Gain” to distinguish between oxidizing and reducing agents.
