Chapter 14 Chemical Effects of Electric Current

  • Some liquids are good conductor of electricity and some are poor conductors.
  • Most of the liquids that conduct electricity are the solution of acid, base and salt.
  • The passage of an electric current through an conducting liquid causes chemical reactions and these final resulting effects are called chemical effects of current.
  • The process of depositing a layer of any metal on another material with the electricity is called electroplating.
  • Positive terminal of the cell is connected to the negative terminal of another cell. Such combination of two or more cells is known as battery.
  • The substances which allows the electric current to pass through them are called as good conductor of electricity.
  • The substances which does not allow the electric current to pass through them are called as bad conductor of electricity.
  • Electrode may be defined as the conductor through which electricity or current enters or leaves.
  • A semi-conductor device which is used in mobiles, computers and torches are known as LED (Light emitting Diode).
