(note: this is a reposting of part of my original post which I was told had too many questions in one post)
Please bear with me as I am a chemistry newbie, but I am autistic and have recently developed a fixation on electrosynthesis and must understand it.
I'm interested in split reaction systems, where a salt bridge connects two chambers, and an aqueous media is used. I'll try to split my questions about this into two sections; water alone, and organic synthesis that take place in water.
In the anode chamber, with the use of a catalytic anode (platinum, platinized titanium, palladium, etc), will the free radicals form hydroxides, peroxide, etc. just build up if the water is stirred properly? Or will ions coming across the salt bridge balance it out somehow? I am confused about that because I thought the point of the salt bridge is to isolate half reactions. So I assume you get unbalanced results isolated in each chamber?
When you add a complex organic molecule, how do the electrochemists keep the side-reactions from trashing their molecules? Do they have to factor in the water reactions as part of their strategy to reduce or oxidize the compound?
