Actually, I'm retarded, alkaline and acid solutions are usually electrically neutral overall due to their increased affinity to ions from various electrolytes. In the case of the body, any overall positive or negative charge is managed by the process of homeostasis, and the affinity for these electrolytes keeps things in check. So I was wrong that it's overall becoming more positive or more negative, oops.

So adequate electrolyte intake is essential for the management of acidity and charge, as is the maintenance of a good many other things which your body automatically uses to manage these aspects of your interstitial tissues and facilitate the electrochemical processes for life.
