question_answer 1)

Consider the reaction of water with \[{{F}_{2}}\] and suggest in terms of oxidation and reduction, which species are oxidised/reduced.

Answer:

\[2{{F}_{2}}(g)+2{{H}_{2}}O(l)\to {{O}_{2}}(g)+4HF(aq)\] \[3{{F}_{2}}(g)+3{{H}_{2}}O(l)\to {{O}_{3}}(g)+6HF(aq)\] In these reactions, water acts as a reducing agent as it gets oxidised to either \[{{O}_{2}}\] or \[{{O}_{3}}\] while fluorine acts as an oxidising agent as it is reduced to \[{{F}^{-}}\] ion.
