Ag/AgCl Reference Electrode
The Ag/AgCl reference electrode is a compact, mercury‑free element used in aqueous electrochemical measurements. It consists of a silver wire coated with AgCl in a chloride electrolyte (typically saturated or 3 M KCl), providing a stable potential of about +0.197 V vs SHE at 25 °C. Ideal for CV, potentiometry, corrosion studies, and sensors, it offers low drift and long‑term reliability.

Description
The Ag/AgCl (silver/silver chloride) reference electrode is a highly reliable, mercury‑free reference element widely used in aqueous electrochemical measurements. It consists of a silver wire coated with a thin layer of silver chloride, immersed in a chloride‑containing electrolyte (typically saturated or 3 M KCl), providing a stable and well‑defined potential. At 25 °C with saturated KCl, its potential is approximately +0.197 V vs SHE, making it ideal for cyclic voltammetry, potentiometry, corrosion studies, and sensor applications. The electrode is compact, refillable, and compatible with neutral to slightly acidic environments, ensuring long‑term stability and minimal potential drift in routine laboratory work.
