Let us consider balancing the redox reaction that occurs between bromite and thiosulfate to form bromine and sulfate at a high pH. The unbalanced form of the reaction is shown below. ?BrO2−(aq) + ?S2O32−(aq) → ?Br2(l) + ?SO32−(aq) The final balanced equation will also include water molecules and hydroxide ions, but first balance the half-reaction for the reduction. Write a balanced half-reaction, including any necessary water molecules, hydroxide ions, and electrons, for the reduction of BrO2−(aq) to Br2(l).
