Product Overview

Description

The Silver Silver Chloride Electrode paste

Basic Principles

The silver/silver chloride electrode is a reference electrode of the second kind where the metal (silver) is in contact with a slightly soluble salt (silver chloride) containing the metal, which in turn is in contact with a solution containing the common anion (chloride ion). The ions in the solid phase and those in the liquid phase are in equilibrium. 

Ag solid  =   AgCl solid  =  Cl  solution 

The potential of the electrode is dependent on the concentration of the chloride ions in solution and temperature as governed by the Nernst equation.
 
ET  = E0 - RT/nF  ln Cl-   (in moles/litre)  

ET = Electrode Potential measured in Volts between a metal electrode (steel structure) and a reference electrode
E0 = Electrode Standard Potential
R = Universal gas constant
F = Faraday constant
T = Temperature
n = Number of moles
Cl = Chloride ions
