I'm confused as to how eletrolysis work. More specifically, how does one oxidize, for example, benzidine electrochemically?

Well, start with something simpler:  Say you send a current through plain water (and pretend that that works easily, usually we need a non-reacting ionic salt to help the current flow.)  What do you get at each electrode, and why?  What is oxidized, and what is reduced?  What hill happen to a solution of benzidine in that case?
