6k.5 7th ed. Writing half reaction for basic solution

Postby JulieAljamal1E » Wed Feb 20, 2019 7:07 pm

For part a) we need to balance the skeletal equation O3+Br- ---> O2+BrO3- using oxidation and reduction half reactions taking place in a basic solution. Would O3-->O2 be oxidizing or is that a reduction? I think it's oxidizing, but later when the solutions shows the half reaction, it gives H2O+O3+ 2e- --> O2+2OH-... I'm confused because they add the 2 electrons to the left side, but the book says you add the electrons to the left side when it's a reducing reaction. But here isn't O3 oxidizing thus we should add electrons to the right side?

I'm actually struggling with grasping that subject too. I also thought it was oxidizing.
