Redox Reactions

Question

Fluorine reacts with ice and results in the change:
H₂O(s) + F₂(g) → HF(g) + HOF (g)
Justify that this reaction is a redox reaction.

Answer

In a redox reaction, one of the reacting species is to undergo an increase in Oxidation Number and other must undergo a decrease in Oxidation Number based upon this, the given reaction is redox reaction.

Here F₂ is oxidised to HOF and reduced to HF, therefore it is a redox reaction.
