Why does the following reaction occur ?
`XeO_(6)^(4-)(aq)+2F^(-)(aq)+6H^(+)(aq)toXeO_(3)(g)+F_(2)(g)+3H_(2)O(l)`
What conclusion about the compound `Na_(4)XeO_(6)` (of which `XeO_(6)^(4-)` is a part) can be drawn from the reaction.

Explanation

The perxenate ion `XeO_(6)^(4-)` ion is very strong oxidising agent than fluorine. So it can oxidise `F^(-)` ion to fluorine in acid medium. Hence the reaction occurs.
`XeO_(6)^(4-)(aq)+2F^(-)(aq)+6H^(+)(aq)toXeO_(3)(g)+F_(2)(g)+3H_(2)O(l)`
