  "term": "Ion-selective electrode cell",
  "field": "Chemistry",
  "definition": "An electrochemical cell constructed for the potentiometric measurement of a specific ion's activity in a solution. It consists of an ion-selective electrode, which responds to the target ion, and a reference electrode, which maintains a constant potential, both immersed in the sample solution. The potential difference between these two electrodes is measured to determine the ion activity.",
