  "id": "MLC-T-CHM-006680",
  "term": "Liquid junction",
  "field": "Chemistry",
  "definition": "The interface between two electrolyte solutions of different compositions or concentrations, which gives rise to a potential difference known as the liquid junction potential. This potential arises from the differing mobilities of ions across the interface. It is a common component in electrochemical cells, particularly reference electrodes.",
