GSC International N-00019 Daniel Cell Full Set. For Chemical Battery Experiments. With Propeller Motor and Electric Buzzer. The set provides a hands-on demonstration of fundamental electrochemical principles.
Purpose: Designed for chemical battery experiments, the Daniell Cell Basic Set minimizes the use of chemicals and reduces waste fluid, saving time in post-experiment waste treatment. This makes it an environmentally considerate choice for classroom and laboratory use.
Innovative Design: The set features separate positive and negative electrode cells that interact to generate electromotive force through controlled chemical reactions. This kit provides a more expansive set of component parts than the basic kit. A #N-00003 DC Voltmeter is useful to compare the electromotive forces of different metal combinations.
Historical Context: The Daniell cell, invented in 1836 by J. F. Daniell, was developed to address limitations of the Voltaic cell. It ensures a longer operational life by preventing hydrogen buildup, a key issue in the Voltaic cell, through the use of a separator.
Chemical Process: The reaction involves zinc at the negative electrode undergoing ionization (Zn → Zn²⁺ + 2e⁻) and copper ions at the positive electrode being reduced to solid copper (Cu²⁺ + 2e⁻ → Cu). This transfer of electrons generates a theoretical electromotive force of 1.07V under ideal conditions.
Educational Value: The set provides a hands-on demonstration of fundamental electrochemical principles, including ion exchange, electron flow, and redox reactions. Its simplified structure allows students to focus on understanding the concepts while fostering safe and efficient experimentation.
