Hey everyone, I'm having trouble with balancing redox reactions that involve many ions, I'm having difficulty determining the half reactions, for example:
H2SO4(aq)+NaBr(s)⟶Br2(l)+SO2(g)+Na2SO4(aq)+H2O(l)
I can see that Br is getting oxidized (-1 > 0), and is the sulfur being reduced? (+6 in H2SO4 and +4 in SO2)
But what would the half reactions be? I think it's the polyatomic ions that confuse me. Thanks for any help!
