A halogen can also replace another halogen from a compound: The activity of halogens

A halogen can also replace another halogen from a compound: The activity of halogens decreases as you go down Group 7 A of the periodic table (F, Cl, Br, & I). Br 2(aq) + 2 Na. I(aq) → 2 Na. Br(aq) + I 2 (aq) * Bromine is more active than iodine, so the reaction occurs. Br 2(aq) + Na. Cl(aq) → N/R * But bromine is less active than chlorine, so this reaction does not occur.
