Base-catalyzed mechanism: what does it look like?

Hello folks, We checked our chemistry homework today, and I got almost everything wrong in this problem. I wanted to ask you how to identify everything in this problem. The reaction equation is: 5SO3^2-(aq) + 2MnO4^-(aq) + 6H3O^+(aq) –> 5SO4^2-(aq) + 2Mn^2+(aq) + 9H2O The tasks are: a) Place the two redox pairs b) Name…
