Physics - Chemical Effects of Electric Current



  • Most of the liquids that conduct electricity belong to solutions of acids, bases and salts.

  • Some liquids are good conductors and some are poor conductors of electricity.

  • The passage of an electric current through a conducting liquid normally causes chemical reactions and the resulting effects of this reaction are known as chemical effects of currents.

  • The process of depositing a layer of any desired metal on another material by means of electricity is known as electroplating.

  • Electroplating is commonly used in industry for coating metal objects with a thin layer of a different metal.

Electroplated Object
  • Coating of zinc is applied on iron to protect it from the corrosion and formation of rust.
