Question
Bromine is commercially prepared from sea water by displacement reaction<br>Cl2 + 2Br-(aq) $\rightarrow$ 2Cl-(aq) + Br2<br>Br2 gas thus formed is dissolved into solution of Na2CO3 and then pure Br2 is obtained by treatment of the solution with :
Answer: C
💡 Solution & Explanation
3Br2 + 3Na2CO3 (impure) $\rightarrow$ 5NaBr + NaBrO3 + 3CO2$\uparrow$<br>5NaBr + NaBrO3 + H2SO4 $\rightarrow$ 3Br2$\uparrow$ (Pure) + Na2SO4
