Suspension potentiometric cell

  "id": "MLC-T-CHM-011703",
  "term": "Suspension potentiometric cell",
  "field": "Chemistry",
  "definition": "An electrochemical cell designed for potentiometric measurements, such as pH, in a multiphase system containing suspended solid particles. The setup includes a sensing electrode and a reference electrode immersed in the liquid phase of the suspension, which is kept homogeneous by stirring. A key challenge is the suspension effect, a junction potential that arises at the interface between the reference electrode's salt bridge and the suspension.",
