Leclanche Cell Apparatus for Laboratory Use

Leclanche Cell Apparatus is a physics and chemistry lab apparatus used for physics and chemistry practical experiments in the Laboratory. The Leclanche Cell Apparatus is for training and education only.

The Leclanché cell apparatus is an electrochemical device used to convert chemical energy into electrical energy through a redox reaction. Invented by Georges Leclanché in the 1860s, it was one of the first types of batteries and is still significant in educational settings for demonstrating basic principles of electrochemistry.

• The Leclanche Cell is commercially called a dry cell.
• A zinc rod with a terminal and for the anode, a filled porous pot is supplied.
• Approx. 500 ml of ammonium chloride electrolyte supplied without electrolyte.
• It consists of either a glass or a plastic container 95 x 95 x 150mm (length x width x height).
• A carbon anode with the terminal is sealed in a filled porous pot containing the depolarizer.
• Made in India

Key Components of Leclanche Cell Apparatus:

• Anode: Typically made of zinc, which serves as the negative electrode and is oxidized during the reaction.
• Cathode: Usually composed of a carbon rod surrounded by manganese dioxide, which acts as the positive electrode.
• Electrolyte: A paste or solution of ammonium chloride (NH4Cl) mixed with water, which facilitates the flow of ions.

Working Principle:

In the Leclanché cell, zinc oxidizes at the anode, releasing electrons, while the manganese dioxide reduces at the cathode, accepting electrons. This flow of electrons generates an electric current that can be harnessed for various applications.

General Applications of this apparatus:

• Educational Tool: Often used in laboratories to teach the principles of electrochemistry and battery technology.
• Simple Battery: Historically used in applications like doorbell circuits and small flashlights.

The Leclanché cell remains an important part of the study of electrochemical systems, providing insights into battery technology and energy conversion.

Precautions

• Handle with Care: The apparatus contains chemicals that may be harmful if spilled or mishandled.
• Wear Protective Gear: Always use gloves and goggles when conducting experiments to prevent contact with the electrolyte.
• Avoid Short Circuits: Ensure that connections are secure to prevent short-circuiting the cell, which could cause overheating or damage.
