Marks: +1, -0

Consider the reaction of water with

\mathrm{F}_2

and suggest, in terms of oxidation and reduction, which species are oxidised/reduced?

Solution:

2\mathrm{F}_{2(g)} + 2\mathrm{H}_2\mathrm{O}_{(l)}

→

4\mathrm{H}^+_{(aq)} + 4\mathrm{F}^-_{(aq)} + \mathrm{O}_{2(g)}

In this reaction,

\mathrm{H}_2\mathrm{O}

is oxidised to oxygen by

\mathrm{F}_2

. Fluorine has been reduced to F– ion.
