Process of electrolytic conduction:

The electrons are received from the negative end of the external battery by the negative electrode of the cell. These are used up in the reduction reaction at this electrode. The numbers of electrons received at the negative electrode are given back to the positive end of the external battery from the positive electrode of the cell where electrons are released as the result of oxidation reaction. In the cell, current is carried by the movement of ions; cations moves towards negative electrode called the cathode and anions towards the positive electrode called anode. This movement of ions gives rise to what is known as the electrolytic conduction. The latter, thus, depends on the mobility of ions and anything that inhibits the motion of ions causes resistance to current flow. Factors which influence an electrical conductivity of solutions of electrolytes involve interionic attraction, solvation of ions, and viscosity of solvents. These factors depend on the attraction that is. solute-solute, solute-solvent and solvent- solvent respectively. An average kinetic energy of the solute ions increases as the temperature is raised and, thus, the resistance of electrolytic conductors commonly decreases, that is, conduction rise as the temperature is raised.
