| Electrode Type | Electrolyte | Remarks |
|---|---|---|
| Saturated Calomel Electrode (SCE) | Saturated KCl | Double liquid junction, suitable for both acidic and alkaline environments |
| Ag/AgCl Electrode | Saturated KCl | Applicable to acidic and neutral environments |
| Silver Ion Reference Electrode | Self-prepared electrolyte | For non-aqueous systems |
| Mercury/Mercuric Oxide Electrode | KOH solution | Strong alkaline environments |
| Mercury Sulfate Electrode | K₂SO₄ solution | Primarily for sulfuric acid systems |
Reference electrodes require regular electrolyte replacement. The electrode tip should be well protected to avoid drying and blockage.
