Carbon Electrode Rods with terminals, approximately 6 inches in length, are specialized rods primarily used as electrodes in laboratory and industrial applications. These rods are typically cylindrical and made of high-purity carbon or graphite, known for excellent electrical conductivity and heat resistance. Description and Features: Constructed from pure carbon or graphite material with high density and conductivity, ideal for efficient current flow. Equipped with metal terminals (often brass or copper) at one or both ends, facilitating secure electrical connections to power sources or devices. Approximately 6 inches in length (around 150mm), suitable for use in laboratory experiments, electrolysis, arc welding, and industrial processes requiring stable and durable electrodes. The rods are resistant to high temperatures and chemical reactions, exhibiting durability under harsh electrical and thermal conditions. Commonly used for arc welding applications, electrochemical cells, and as electrodes in various scientific and manufacturing processes. The terminal fittings ensure efficient electrical contact, reduce resistance losses, and provide mechanical stability. These carbon electrode rods with terminals offer reliable performance, longevity, and ease of use in electrical and thermal applications where stable, conductive electrodes are essential

A Daniel Cell is a type of electrochemical (galvanic) cell that converts chemical energy into electrical energy through a spontaneous redox reaction involving zinc and copper. It was invented in 1836 by John Frederic Daniell and marked a significant advancement in battery technology by addressing limitations found in earlier voltaic cells. Construction The Daniel Cell consists of two half-cells: Zinc electrode in zinc sulfate (ZnSO₄) solution: This forms the anode (negative electrode), where zinc undergoes oxidation, releasing electrons and forming zinc ions into the solution. Copper electrode in copper sulfate (CuSO₄) solution: This acts as the cathode (positive electrode), where copper ions from the solution accept electrons and get deposited as metallic copper on the electrode (reduction). The two solutions are usually separated by a porous membrane or a salt bridge, which maintains electrical neutrality by allowing ion flow, but prevents the solutions from mixing directly. Working Principle The Daniel Cell operates based on the following redox reactions: At the anode (zinc): Zn (s) → Zn²⁺ (aq) + 2e⁻ (oxidation). At the cathode (copper): Cu²⁺ (aq) + 2e⁻ → Cu (s) (reduction). Electrons released at the zinc electrode travel through the external circuit to the copper electrode, generating an electric current. Simultaneously, the salt bridge or porous membrane allows ions to flow between the solutions to maintain charge balance. The overall cell reaction is: Zn (s) + Cu 2 + ( aq ) → Zn 2 + ( aq ) + Cu (s) Zn (s) + Cu 2+ (aq)→Zn 2+ (aq)+Cu (s) This reaction typically provides a voltage of around 1.1 V under standard conditions. Features and Applications Efficiently transforms chemical energy into electrical energy. Reliable, steady source of voltage, making it a reference for the standard definition of the volt. Historically used as a power source for telegraphy and experimentation in electrochemistry. Demonstrates the fundamental principles of batteries and galvanic cells, and is commonly studied in chemistry and physics classes. The Daniel Cell remains an important educational and scientific tool for illustrating basic electrochemical reactions and the conversion of chemical to electrical energy.
