The aqueous phase in contact with the mercury and the mercury (I) chloride (Hg 2 Cl 2, " calomel ") is a saturated solution of potassium chloride in water. The electrode is normally linked via a porous frit to the solution in which the other electrode is immersed. This porous frit is a salt bridge. electrode in ZoBell’s at 25°C) is the measured potential of the calomel (Hg:HgCl 2) electrode; E° = 430 mV is the standard electrode potential of ZoBell’s solution measured against the hydrogen electrode at 25°C. Half-cell potentials for the calomel, silver:silver chloride, and combi-nation electrodes are shown in table 6.5–2.

1. Overview and Key Difference 2. What is a Calomel Electrode 3. Electrochemical polymerization of EDOT on the HNT-modified alkali-treated Ti alloy was done in a three-electrode cell arrangement using cyclic voltammetry (CV CHI 760C electrochemical workstation (USA)) in which the alkali-treated Ti alloy and platinum electrodes were the working electrode and counterelectrode, and saturated calomel electrode (SCE) served as the reference electrode, respectively. 2021-04-23 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: . A temperature of 298.15 K (25.00 °C; 77.00 °F). An effective concentration of 1 mol/L for each aqueous species or a species in a mercury amalgam (an alloy of mercury with another metal).

The calomel electrode consists of a broad glass tube having sidearm as shown in the figure. The sidearm is used for dipping it any solution used for coupling the calomel electrode. At the bottom of the glass tube, there is pure mercury and a platinum wire is sealed into it at the bottom for electrical connections. The most widely used reference electrodes for redox potential measurement are the calomel (mercury–mercurous chloride) and the silver⧸chloride electrode.
The electrode is based on the redox reactions. Redox reactions: involve transfer of electrons from one species Example: Balance the two half reactions and redox saturated calomel electrode is 0.241 V.
