| Abstrakt: | SATURATED or 3 molar potassium chloride salt bridges connected to a calomel half cell or a silver–silver chloride electrode are used extensively in electrochemistry and electrophysiology as reference electrodes for potential measurements. The 3 molar potassium chloride salt bridge electrode is used in electrophysiology primarily because the liquid junction potential from the salt bridge to physiological solutions is only a few millivolts and varies little at equilibrium when in different physiological solutions. Derivations for this liquid junction potential have been obtained1–3. |
