Cathodic (adjective)

Relating to a cathode, the electrode of an electrochemical cell at which reduction occurs.

Origin:

Derived from the greek word "kathodos", meaning "downward" or "descending".

Examples:

  1. In a galvanic cell, the cathodic electrode is the electrode at which the reduction reaction occurs, and electrons are produced.
  2. The cathodic protection of a metal surface involves applying a low voltage to the metal, which prevents corrosion by reducing the rate of oxidation.
  3. Cathodic protection is often used to preserve the integrity of pipelines, ships, and other metal structures in harsh environments.
  4. In cathodic electrodeposition, metal ions are reduced at the cathodic electrode, depositing a layer of metal on the surface.
  5. The cathodic current density is an important parameter in the design and performance of cathodic protection systems, as it determines the rate at which electrons are produced.
