Electrolysis

Electrolysis:

Electrolysis is the process by which an element is decomposed and undergoes some chemical change under the influence of any electric current. The first-ever electrolysis was executed out by Sir Humphrey Davey in the year 1808. Electrolysis can occur in both Galvanic cells and Electrolytic cells. 

Applications of Electrolysis:

  1. Electrolytic cells are used for the production of Hydrogen and Oxygen gas from water.
  2. They are used for the large-scale production of pure metals like sodium, copper, magnesium, etc.
  3. They are used to extract Aluminium from Bauxite.
  4. Electrolytic cells are used for electroplating, a process by which a thin protective layer of one metal is formed over another metal, mostly for protection.
  5. Electrolysis is used for the electrorefining of non-ferrous metals.
