What is reference electrode

Reference electrode) and an actual reference electrode.The electrode potential of any other electrode that can be measured is called a reference electrode.Electrode potentials vs she for the two reference electrodes in the dataset using \(\ce{kcl(aq)}\) electrolyte (each panel shows one reference electrode, each line shows a different electrolyte concentration).Using reference electrodes unknown potential of any other single electrode can be found out e.g.The indicator electrode possesses some characteristic that allows it to selectively respond to changes in the activity of the analyte being measured.

Reference electrode allows you to measure the potential of the working electrode with out passing current through it while counter (auxiliary) electrode allows you to pass current.These reference electrodes, above, all need a salt bridge which is a junction or portal that connects the internal electrolyte solution of the electrode to the external sample solution.The high stability of the electrode potential is usually reached by employing a redox system [clarification needed] with constant (buffered or saturated) concentrations of each participant of the redox reaction.Reference electrode a chemical electrode whose cell potential remains fixed and against which an indicator electrode is compared.Ag/agcl is great because of this.

Reference electrode reactions, like all r eversible electrochemical reactions , can be described by equation 1 , 𝑂𝑂𝑂𝑂+ 𝑛𝑛𝑛𝑛⇌𝑅𝑅𝑛𝑛𝑑𝑑 ( 1 ) where 𝑂𝑂𝑂𝑂 and 𝑅𝑅𝑛𝑛𝑑𝑑 describe the oxidized and reduced species, respectively, and represents the number of 𝑛𝑛 electrons, 𝑛𝑛, passed during the electrochemical reaction.What is a reference electrode?
