About this document
Citrus Fruit Battery Experiment Analysis by Natalie Ma is a document available to read on EtoBox.
The student will investigate how different citrus fruits with varying pH levels affect the electrical current produced when used as the electrolyte in a fruit battery. Lemons, limes, grapefruits, and oranges will each be tested using a copper and zinc electrode to measure current in amps. Based on research showing that lower pH means higher hydrogen ion concentration and stronger "pull" of electrons, the student hypothesizes that current will increase as pH decreases, predicting lemons will produce the high
