$Br$ and $As$

Vedclass · Answer

(B) In the reaction $3 H_3AsO_3 + BrO_3^- \rightarrow Br^- + 3 H_3AsO_4$,we assign oxidation numbers:For $BrO_3^-$,the oxidation state of $Br$ is $+5$. In $Br^-$,it is $-1$. Since the oxidation number decreases from $+5$ to $-1$,$Br$ undergoes reduction.For $H_3AsO_3$,the oxidation state of $As$ is $+3$. In $H_3AsO_4$,it is $+5$. Since the oxidation number increases from $+3$ to $+5$,$As$ undergoes oxidation.Therefore,$Br$ undergoes reduction and $As$ undergoes oxidation.

Identify the elements undergoing reduction and oxidation respectively in the following redox reaction.
$3 H_3AsO_{3(aq)} + BrO_{3(aq)}^{-} \rightarrow Br_{(aq)}^{-} + 3 H_3AsO_{4(aq)}$
