  "id": "MLC-T-CHM-004893",
  "term": "Glass pH-sensitive electrode",
  "field": "Chemistry",
  "definition": "An electrochemical sensor designed to measure the hydrogen ion activity (pH) of a solution, consisting of a thin glass membrane that develops a potential difference proportional to the pH gradient across it. The potential is measured against a reference electrode, and the response follows the Nernst equation. This electrode is widely used for routine pH measurements in laboratories and industry.",
