Hw problem 6k.5 b)

Postby Amy Luu 2G » Sat Feb 22, 2020 4:55 pm

Balance each of the following skeletal equations by using oxidation and reduction half-reactions. All the reactions take place in basic solution. Identify the oxidizing agent and reducing agent in each reaction.
b) Br2(l) ---> BrO3-(aq) + Br-(aq)

For this problem, I am unsure how to find the half reactions. Does Br2 act as both an oxidizing and reducing agent? if so how would i write the half reactions?

I believe that you would assume that it is both an oxidizing and reducing agent. You should still split the reaction into 2 half reactions. Br2 --> Br- is the reduction reaction (0 to 1-) and Br2 --> BrO3- is the oxidation reaction (0 to 5+).

Br2 is both the oxidizing and reducing agent since it is the only reactant. You have the balance the reduction half reaction and the oxidation half reaction and then combine both reactions.
