Conduction of electricity is the movement of the charged particles in an organized manner resulting in a net movement of charge through the material. When charged particles move in an appropriate motion we get an electric current.
- The conduction of electricity through a solution involves the movement of charged particles. The phenomena associated with electrical conduction through gases have found many applications in modern technology.
- Electricity flows through conductors in one of two ways.
(i) The first is by electron movement as in the case with most metals.
(ii) The other type of flow is by ionic movement, which may be charged atoms or molecules.
To explain electrolytic conduction which is a current flow through a liquid sulphuric acid is the best electrolyte example to choose.
- In an aqueous solution, sulphuric acid dissociates into 2H+ and So42-, which are positive and negative ions
- The positive charges are attracted to the negative electrodes and the negative charges are attracted to the positive electrode.
- This movement is known as ion flow or ion drift.
