  "id": "MLC-T-CHM-010062",
  "term": "Reference electrode",
  "field": "Chemistry",
  "definition": "An electrode that maintains a stable and known potential, serving as a benchmark against which the potential of other electrodes in an electrochemical cell is measured. It provides a constant half-cell potential, allowing for accurate determination of the potential of a working electrode. Common examples include the standard hydrogen electrode, calomel electrode, and silver/silver chloride electrode.",
