Abstract

A reference electrode consisting of a metal in contact in contact with an electrolyte containing an anion or cation whose concentration in part determines the redox potential of the electrode? This electrolyte contains a polyelectrolyte that partially and reversibly binds this chemical cation or anion thus lowering the free concentration of the cation or anion compared to the osmotic pressure of the same concentration of cation or anion if present as a simple salt. The polyelectrolyte can be anionic or cationic depending on the chemistry of the redox electrode and a thickener may also be added to the electrolyte.
