उत्तर
The reaction between fluorine and water can be represented as:
\[\ce{2F_{2(g)} + 2H_2O_{(l)} -> 4H^+_{(aq)} + 4F^-_{(aq)} + O_{2(g)}}\]
This is an example of a redox reaction as water is getting oxidized to oxygen, while fluorine is being reduced to fluoride ion.
The oxidation numbers of various species can be represented as:

Fluorine is reduced from zero to (- 1) oxidation state. A decrease in oxidation state indicates the reduction of fluorine.
Water is oxidized from (- 2) to zero oxidation state. An increase in oxidation state indicates oxidation of water.
