redox reaction

a redox reaction can be understood as follows:

• Oxidation:

  • Addition of oxygen to a substance.
  • Removal of hydrogen from a substance.

• Reduction:

  • Removal of oxygen from a substance.
  • Addition of hydrogen to a substance.

Examples Based on This Concept

1. Oxidation of Carbon to Carbon Dioxide

   C + O2 -------> CO2

2. Reduction of Copper Oxide

   CuO + H2 --------->Cu + H2O

• H₂ gains oxygen and gets oxidized to H₂O.

3. Oxidation of Hydrogen Sulfide

   H2S + Cl2 -------> S + 2HCl

• Cl₂ gains hydrogen and gets reduced to HCl.
