In the following chemical reaction  2Br-+ X2 â†’Br2+ 2X-, X2 is

2Br-+ Cl2 â†’ Br2+ 2Cl-  Chlorine does not oxidize fluoride, but liberates bromine and iodine from their respective aqueous halide salts. Because  higher standard electrode potential element replace the lower standard electrode potential element from their salts
