what kind of reactions require oxidizing agent(reduced or oxidized) for example SO3->SO4 does it require oxidizing or reducing agent why?

I know what you're asking but I think you gave the wrong example. Is that SO3^2- ==> SO4^2-. If so, then S on the left is +4 and S on the right is +6 so the change is -2 electrons. Since oxidation is the loss of electrons then SO3^2- must be oxidized. That means SO3^2- is the reducing agent (it is oxidized) so you want an oxidizing agent to oxidize sulfite to sulfate.
what about 2Br^- ===>Br2
What about it.
Go through the same reasoning and I'll check it for you. Remember the definitions.
Oxidation is the loss of e.
Reduction is the gain of e.
The material oxidized is the reducing agent.
The material reduced is the oxidizing agent.
