One compartment contains a silver wire inserted into a 1.0 M solution of Ag +, and the other compartment contains a silver wire inserted into a 1.0 M Cl − solution saturated with AgCl. The saturated calomel electrode (SCE) is a reference electrode based on the reaction between elemental mercury and mercury(I) chloride.It has been widely replaced by the silver chloride electrode, however the calomel electrode has a reputation of being more robust. This chemistry video tutorial explains how to calculate the standard cell potential of a galvanic cell and an electrolytic cell.

Ag 2 O or AgOH will form if the [OH-] is on the order of 0.1 M and the electrode potential will be a mixed Ag/AgCl/Ag 2 O potential and will depend on the pH. 2020-01-10 2016-07-04 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 Electrochemical Cell Potentials. 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).Determining Standard State Cell Potentials 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. solution then the potential is +0.197V.

NHE 25 C D.J.Ives and G.J.Janz, "Reference Electrodes," Academic Press, New York, 1961 The data values of standard electrode potentials (E°) are given in the table below, in volts relative to the standard hydrogen electrode, and are for the following conditions: Dip your made Ag/AgCl reference electrode in a beaker with 1 M HCl solution and take a Pt foil in to the beaker, pursue with H 2 gas (thus the E0 of the hydrogen electrode will not be 0.00V The Ag/AgCl electrode is by far the most popular type of laboratory reference electrode in use today. 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.
