Solution :-

The reaction between water and fluorine can be represented as:

\( 2F_{2(g)}+2H_{2}O_{(l)}\rightarrow 4H^{+}_{(aq)}+4F^{-}_{(aq)}+O_{2(g)} \)

This is an example of redox reaction

\( 2F_{2(g)}+2H_{2}O_{(l)}\rightarrow 4H^{+}_{(aq)}+4F^{-}_{(aq)}+O_{2(g)} \)

Water is getting oxidized to oxygen and fluorine is being reduced to fluoride ion.

The oxidation number of various species can be represented as:

\( 2F_{2(g)}+2H_{2}O_{(l)}\rightarrow 4H^{+}_{(aq)}+4F^{-}_{(aq)}+O_{2(g)} \)

Water is oxidized from (– 2) to zero oxidation state. An increase in oxidation state indicates oxidation of water.

Fluorine is reduced from zero to (– 1) oxidation state. A decrease in oxidation state indicates the reduction of fluorine.
