If you just have an aqueous electrolyte with virtually no H+ or OH- ions (neutral), will water spontaneously produce them if required? e.g.

I see but where is that in the original equation?

It was just an example. You could use a few other half equations to balance, i think, e.g.

Yes, but not nearly enough for any significant rate of reaction. (Around ~)

This half-equation needs an acidified conditions in order to operate functionally (and 1M for electrochemical series to work)

P.S.: Excited to be unveiling a great and free solution to these kind of short (but important and conceptual) questions soon!

Combine with the previous half equation with the H+
