  "id": "MLC-T-CHM-002633",
  "term": "Counter electrode",
  "field": "Chemistry",
  "definition": "An electrode in an electrochemical cell that completes the electrical circuit and allows current to flow, without necessarily being the site of the primary analytical reaction. Its purpose is to provide a pathway for electrons to balance the reaction occurring at the working electrode. It is typically designed to have a large surface area to minimize its own polarization.",
