Electrochemistry & Redox

A reference electrode based on the equilibrium between mercury, mercury(I) chloride and chloride ions.

Hg₂Cl₂ + 2e⁻ ⇌ 2Hg + 2Cl⁻ V

The electrode at which reduction occurs.

Dimensionless

Electrochemistry & Redox

The prevention of corrosion by forcing the metal to be protected to act as a cathode.

V

Electrochemistry & Redox

A shorthand convention for representing an electrochemical cell using vertical lines for phase boundaries.

Zn(s) | Zn²⁺(aq) ‖ Cu²⁺(aq) | Cu(s) Dimensionless

Electrochemistry & Redox

The difference in electrical potential between the two electrodes of an electrochemical cell.

E_cell = E_red(cathode) − E_red(anode) V

Electrochemistry & Redox

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) V

Electrochemistry & Redox

A titration in which the end point is found from changes in the conductivity of the solution.

S/m

Electrochemistry & Redox

The gradual destruction of a metal by electrochemical reaction with its environment.
