20 " mL of " `(M)/(60)` `KBrO_3` was reacted with a sample of `SeO_(3)^(2-)` 20 The `Br_(2)` thus evolved was removed and the excess of `NaAsO_(2)` The reaction involved are `SeO_(3)^(2-)+BrO_(3)^(ɵ)+H^(o+)toSeO_(4)^(2-)+Br_(2)+H_(2)O` .. (i) `BrO_(3)^(ɵ)+ASO_(2)^(ɵ)+H_(2)OtoBr^(ɵ)+AsO_(4)^(3-)+H^(o+)` ..(ii) `[Mw(SeO_(3)^(2-))=79+48=127gmol^(-1)]` Q. m" Eq of "`SeO_(3)^(2-)` isA. `(55)/(72)`B. `(55)/(36)`C. `(11)/(36)`D. `(11)/(6)` |

Answer» Correct Answer - B m" mol of "`BrO_(3)^(ɵ)` reacted with `SeO_(3)^(2-)` in equation (i) `=(11)/(36) m" mol of "BrO_(3)^(ɵ)` `=(11)/(36)xx5` (n-factor `BrO_(3)^(ɵ)` in equation (i)) `=(55)/(36)m" Eq of "BrO_(3)^(ɵ)-=m" Eq of "SeO_(3)^(2-)` reacrted |
