Simple Potato Battery
Select two different metal strips and one potato. Use a copper and a zinc coated metal strip. We need galvanized metal so the zinc can react.
Carefully place the metal strips into the potato.
Congratulations! You have just made a battery! Simple, yes? Now you will learn about your battery.
Now, you may be wonder, what is causing a chemical reaction? Here is the explanation:
1. the potato has a mild phosphoric acid content H3PO4
2. reduction at Cu (copper) electrode:
2H+ + 2e- -> H2 gas
3. oxidation at Zn (zinc) electrode:
Zn -> Zn++ + 2e-
The H3PO4 acid puts the hydrogen ions in solution.
