Balard in 1826 by reacting bromide ions with a solution of Cl 2 dissolved in water. 2 Br - ( aq) + Cl 2 ( aq) Br 2 ( aq) + 2 Cl - ( aq) Webmolecules in the equation to balance the change in oxidation numbers. There are 19 oxygen atoms on the left-hand side of the equation, so there must be one water molecule on the right-hand side and, hence, two hydrogen ions on the left. Note that the overall charge on each side is zero. 5 a) The oxidation number of iodine in I. 2. O. 7. is +7.
