  "term": "Internal filling solution",
  "field": "Chemistry",
  "definition": "An electrolyte solution contained within an ion-selective electrode or a reference electrode, which establishes electrical contact with the internal reference element. This solution typically has a stable composition and ionic strength to maintain a constant potential at the internal electrode interface. It provides a stable reference potential for electrochemical measurements.",
