• # question_answer 14) Fluorine reacts with ice and results in the change: ${{H}_{2}}O(s)+{{F}_{2}}(g)\to HF(g)+HOF(g)$ Justify that this reaction is a redox reaction.

It is a redox reaction in which fluorine is oxidised as well as reduced. $\overset{0}{\mathop{{{F}_{2}}}}\,\to \overset{+1-1}{\mathop{HF}}\,$ (Reduction) ${{F}_{2}}+2{{e}^{-}}\to 2{{F}^{-}}$ (Gain of electron) $\overset{+2-2}{\mathop{{{H}_{2}}O}}\,\to \overset{+10-1}{\mathop{HOF}}\,$ (Oxidation) ${{O}^{2-}}\to [O]+2{{e}^{-}}$ (Loss of electron)
