In the given reaction fluorine is reduced and chlorine is oxidized.
What is oxidation and reduction?
Oxidation is a process in which addition of oxygen or removal of hydrogen and electron takes place, while reduction is a process in which addition of hydrogen & electrons or removal of oxygen takes place.
Given chemical reaction is:
F₂ + 2HCl → Cl₂ + 2HF
- In the above reaction fluorine is reduced as it accepts an electron and increase in it its oxidation state takes from 0 to -1, which shows reduction.
- In the reaction chlorine is oxidized as it losses an electron and decrease in its oxidation state takes from -1 to 0, which shows oxidation.
- Oxidation half reaction is:
F₂ + 2e⁻ → 2F⁻
- Reduction half reaction is:
2Cl⁻ → Cl₂ + 2e⁻
Hence, fluorine is reduced and chlorine is oxidized in the given reaction.
