When

\mathrm{BrO}_3^ -

ion reacts with

\mathrm{B}{\mathrm{r}^ - }

ion in acidic solution

\mathrm{B}{\mathrm{r}_2}

is liberated. The equivalent weight of

\mathrm{KBr}{\mathrm{O}_3}

is :

View answer and explanation

Correct option: C

M/5

Option C (

M/5

) is correct because in the reaction of

BrO_3^-

with

Br^-

BrO_3^-

is converted to

Br_2

. The oxidation state of Br changes from +5 to 0, a change of 5. Therefore, the equivalent weight is M/5.
