Do Concentration Cells Store Charge in Water? Comment on Can Water Store Charge?

Abstract

In a recent article, Ovchinnikova and Pollack (O&P)(1) reported that the persistent pH gradients (>100 min after electrolysis) generated upon charging a simple electrolytic cell (Pt electrodes in dilute aqueous NaCl solutions) imply that "water can store charge", in apparent violation of the principle of electroneutrality in bulk macroscopic fluid phases.
