Question

Identify (a) and (b).

$B{r}_2+\underset{hot}{O{H}^{-}}\to \left(a\right)+\left(b\right)$

$\left(a\right)+\left(b\right)+H^{+}\to B{r}_2$ :

• A. a- $B{r}^{-}$
• B. b- $BrO$
• C. a- $BrO$
• D. b- $Br{O}_3^{-}$
• E. None of the above

Answer 1

Answer: (A), (D)

a- $B{r}^{-}$
b- $Br{O}_3^{-}$

Method is for enriching $B{r}_2$:

$3B{r}_2+6O{H}^{-}\to \underset{\left(A\right)}{5B{r}^{-}}+\underset{\left(B\right)}{Br{O}_3^{-}}$ +$3H_{2}O$

$5B{r}^{-}+Br{O}_3^{-}+6H^{+}\to 3B{r}_2+3H_{2}O$

Hence,option A and D is correct.
