Vedclass · Answer

(C) Bromine is present in sea water in the form of bromide salts like $KBr$ or $MgBr_2$. To extract bromine,chlorine gas $(Cl_2)$ is bubbled through the concentrated sea water (bittern). Since chlorine is a stronger oxidizing agent than bromine,it displaces bromine from the bromide ions according to the following reaction: $2Br^- (aq) + Cl_2 (g) \rightarrow 2Cl^- (aq) + Br_2 (l)$
