Bromate and bromide ion react to form bromine in acidic medium. When the reaction is balanced which statement is incorrect about  $H^{+}\left(aq\right)$

Its coefficient is twice the coefficient of  $B{r}^{-}\left(aq\right)$

Its coefficient is the sum of the coefficients of  $Br{O}_3^{-}\left(aq\right)$  and  $B{r}^{-}\left(aq\right)$

Its coefficient is twice the coefficient of  $Br{O}_3^{-}\left(aq\right)$

Its coefficient is twice the coefficient of  $B{r}_2\left(aq\right)$
