And is this related to oxidation-reduction titrations. if so, how?

Thanks for all your help.

Most pH meters use redox reactions as the mechanism for measuring [H+]. However, this is WAY beyond the scope of required MCAT knowledge. If it does show up on the MCAT it will be fully described.

It is useless to try and prepare for every possible passage they might throw at you. Science has advanced to such a degree that even a PhD might be ignorant of a certain aspect of his field. Just know the basics REAL WELL.

It has to do with membrane potential and ion exchange. Agree with the above, you're not gonna need to know it.
