Calomel Electrode
Electrochemistry & Redox
V
A reference electrode based on the equilibrium between mercury, mercury(I) chloride and chloride ions.
Hg₂Cl₂ + 2e⁻ ⇌ 2Hg + 2Cl⁻
Cathode
Electrochemistry & Redox
Dimensionless
The electrode at which reduction occurs.
Cathodic Protection
Electrochemistry & Redox
V
The prevention of corrosion by forcing the metal to be protected to act as a cathode.
Cell Notation
Electrochemistry & Redox
Dimensionless
A shorthand convention for representing an electrochemical cell using vertical lines for phase boundaries.
Zn(s) | Zn²⁺(aq) ‖ Cu²⁺(aq) | Cu(s)
Cell Potential
Electrochemistry & Redox
V
The difference in electrical potential between the two electrodes of an electrochemical cell.
E_cell = E_red(cathode) − E_red(anode)
Concentration Cell
Electrochemistry & Redox
V
A galvanic cell in which both electrodes are identical and the potential arises solely from a difference in concentration.
E = (0.0592/n) log(C₂/C₁)
Conductometric Titration
Electrochemistry & Redox
S/m
A titration in which the end point is found from changes in the conductivity of the solution.
Corrosion
Electrochemistry & Redox
mm/year
The gradual destruction of a metal by electrochemical reaction with its environment.
