Question

differences between local action and polarization

Answer 1

• The local action of a battery is the deterioration of the battery due to currents that are flowing from and to the same electrode.

• A battery contains one or more electrochemical cells.
• These electrochemical cells have external connections to power electrical devices.
• There are two terminals in a battery; positive terminal or the cathode and negative terminal or the anode.
• Batteries convert chemical energy into electrical energy.

• polarization;
• Polarization is a defect that occurs in simple electric cells due to the accumulation of hydrogen gas around the positive electrode.
• In simple cells, hydrogen gas is evolved as a result of chemical reactions taking place inside the cell.
• When this hydrogen gas is collected around the positive electrode, eventually it causes the insulation of positive electrode from the electrolytic solution.
• This process is known as polarization.
