Expert Answer:

On a commercial scale, bromine is prepared either from sea water (containingNaBr, KBr and MgBr2) or the mother liquor (containing MgBr2) left after crystallisation of chlorides from carnallite. On passing Cl2 gas through these solutions, bromides get oxidised to bromine which is cooled and condensed to Br2 liquid.
 
                 2Br– + Cl2 ———> 2Cl– + Br2
