Question : 16
Total: 30
Why does the following reaction occur ?
XeO64–(aq)+2F(aq)–+6H(aq)+ → XeO3(g)+F2(g)+3H2O(l)
What conclusion about the compound Na4XeO6 (of which XeO64– is a part) can be drawn from the reaction?
Solution:  
IXeO64–(aq)+2F(aq)–+6H(aq)+ → XeO3(g)+F2(g)+3H2O(l)
n this reaction, O.N. of Xe decreases from +8 in XeO64– to +6 in XeO3 while that of F increases from –1 in F– to 0 in F2. Therefore, XeO64– is reduced while F– is oxidised. From this reaction it is concluded that Na4XeO6 is a stronger oxidising agent than F2.
