Electronic Half-Cell Module to Demonstrate an Electrochemical Series and a Citrus Fruit Battery for Remote Students

Herein,two simulated electrochemistry experiments, namely, the(i) electrochemical series, using an electronic half-cell module,and (ii) citrus fruit battery series are demonstrated for undergraduatechemistry students. The demonstration can be performed for in-personand remote students by connecting the electronic half-cell moduleto a computer. Remote students can participate in the demonstrationon the Internet and interact with the instructor and other students.This experiment does not require the use of metal and metal ion solutionsfor the construction of citrus fruit batteries and electrochemicalseries. Therefore, this demonstration is environmentally green, becauseno chemical waste is produced at the end of the demonstration.
