Ag (s) + Cl – (s) → AgCl (s) + e – This electrode usually takes the form of a piece of silver wire coated with AgCl. The coating is done by making the silver the anode in an electrolytic cell containing HCl; the Ag + ions combine with Cl – ions as fast as they are formed at the silver surface.

It is constructed from a silver wire, part of which is 'chloridized' (covered with finely divided silver chloride). There are several ways to do this (see reference 7). The general equation for this conversion at any pH using Ag/AgCl reference electrode is: E(RHE) = EAg/AgCl + 0.059 pH + EoAg/AgCl Where E oAg/AgCl = 0.1976 V at 25 o C and E Ag/AgCl is your working Solution for Calculate the electrode potential of a silver electrode immersed in a 0.2500M solution of KCl using (i) E0 Ag+/Ag=0.799v (b) E0 AgCl/Ag=0.222v Standard Electrode Potentials in Aqueous Solution at 25°C Cathode (Reduction) Half-Reaction: Standard Potential E ° (volts): Li + (aq) + e--> Li(s)-3.04: K + (aq Ag/AgCl reference electrode is a kind of commonly used reference electrodes.

A glass electrode is generally used for this purpose, in which an internal Ag/AgCl electrode is immersed in a 0.10 M HCl solution that is separated from the solution by a very thin glass membrane (part (b) in Figure \(\PageIndex{5}\)). The glass membrane absorbs protons, which affects the measured potential. Ag (s) + Cl – (s) → AgCl (s) + e – This electrode usually takes the form of a piece of silver wire coated with AgCl.

The cell potential (voltage) for an electrochemical cell can be predicted from half-reactions and its operating conditions (chemical nature of materials, temperature, gas partial pressures, and concentrations). To summarize, the potential of the Ag/AgCl electrode depends on the concentration of the solution used in the electrode itself. If you have a sat.

Applications. Commercial reference electrodes consist of a plastic tube electrode body. The electrode is a silver wire that is coated with a thin layer of silver chloride, either physically by dipping the wire in molten silver chloride, chemically by electroplating the wire in concentrated hydrochloric acid or electrochemically by oxidising the silver in a chloride solution.
