14.5A

Postby donnanguyen1d » Sun Feb 18, 2018 4:30 pm

The directions are to balance the redox reaction in basic solution. A. Action of ozone on bromide ions, O3 (aq) + Br - (aq) --> O2 (g) + BrO3 - (aq).

Why does the solutions manual switch it to 02-> 03? how do you know its the Oxygen and not BR that is reduced?

To see which compounds are reduced or oxidized, you have to look at the oxidation states. Br is going from an oxidation state of 1- to 5+ which shows that it's being oxidized.
