(C) The process involves two main steps:$1$. The absorption of $Br_2$ in a hot aqueous solution of $Na_2CO_3$:$3Br_2 + 3Na_2CO_3 	o 5NaBr + NaBrO_3 + 3CO_2 \uparrow$$2$. The recovery of pure $Br_2$ by treating the resulting mixture with concentrated $H_2SO_4$:$5NaBr + NaBrO_3 + 3H_2SO_4 \xrightarrow{\Delta} 3Br_2 + 3Na_2SO_4 + 3H_2O$Thus,$H_2SO_4$ is used to obtain pure $Br_2$.

Bromine is commercially prepared from sea water by displacement reaction:
$Cl_2 + 2Br^{-} (aq.) \to 2Cl^{-}(aq.) + Br_2$
$Br_2$ gas thus formed is dissolved into a solution of $Na_2CO_3$ and then pure $Br_2$ is obtained by treatment of the solution with:
