Consider the following reactions. Br_(2)+OH^(-)rarrBrO_(3)^(-)+Br^(-)+H_(2)O (unbalanced). select the correct statement

Answer»

EQUIVALENT weight of `Br_(2)` when it is reduced to `BR^(-)` is 80
Equivalent weight of `Br_(2)` when it is oxidised to `BrO_(3)^(-)` is 96
Net equivalent weight of `Br_(2)` is 96
It is a DISPROPORTIONATION reaction

Solution :For disproportionate reactions,
`E=E_("red")+E_("ox")=(160)/(2)+(160)/(10)=80+16=96`
