For the following balanced redox reaction:
`2MnO_(4)^(ɵ)+8H^(o+)+Br_(2)to2Mn^(2+)+2BrO_(3)^(ɵ)+2H_(2)O`
if the molecular weight of `MnO_(4)^(ɵ):Br_(2)` and `Br_(2)` be `M_(1)M_(2)` respectively, then

Options

A. equivalent weight of `MnO_(4)^(ɵ)` is `(M_(1))/(5)`
B. Equivalents weight of `Br_(2)` is `(M_(2))/(10)`
C. The n-factor ratio of `MnO_(4)^(ɵ):Br_(2)is1:1`
D. none of these

Answer

A, B

Explanation

(i). `5e^(-)+MnO_(4)^(ɵ)toMn^(2+)`
(ii). `Br_(2)to2BrO_(3)^(ɵ)+10e^(-)`
(iii). `2MnO_(4)^(ɵ)+Br_(2)+8H^(o+)to2Mn^(2+)+2BrO_(3)^(ɵ)+2H_(2)O`
`Ew(MnO_(4)^(ɵ))=(M_(1))/(5)(n=5)`
`Ew(Br_(2))=(M_(2))/(10)(n=6)`
(c). N-factor ratio `((MnO_(4)^(ɵ))/(Br_(2))=(5)/(6)`
