Learning about energy with experiments 2 – Making a vinegar battery

 

 

By Science Columnist Ho-Gwan Ko

 

 

For modern people who use many portable electronics, batteries are a necessity. The inventor of the battery was Italian scientist Alessandro Volta. Volt (V), the unit of electrical pressure, was named after Volta. He succeeded in making the first battery that could continuously provide an electric current using metal in 1800. This battery is called the voltaic pile.


The metals used in the voltaic pile are zinc and copper. It is made by putting the two metals in a diluted sulfuric acid solution and connecting them with wires. The force that drives the electrical current comes from chemical energy. Zinc, which reacts with sulfuric acid, charges electrons and dissolves as electrons. The electrons travel along the wire to the less reactive copper and react with hydrogen ions in the sulfuric acid solution to form hydrogen gas. This reaction continues, making a current flow. Since the electrons move from zinc to copper, zinc becomes the negative (-) pole and the copper the positive (+) pole.


You can reproduce the same reaction at home. However, let’s replace sulfuric acid with vinegar as it can be dangerous. Vinegar is also an acidic solution that reacts with zinc. You can obtain zinc from galvanized nails and copper from copper wires. You can see if electricity is flowing with an LED bulb. Keep in mind that LED bulbs are polarized; they should be connected accordingly. The more nails you use, the brighter the light will be.

 

What you need: an ice tray, copper wires, galvanized nails, vinegar, an LED bulb.

1. Wrap a copper wire around a nail. Make five of them as shown in the picture.

2. Put the nails in an ice tray. Put each nail and its copper wire in different compartments.

3. Put the rest of the nails in each compartment. Refer to the image and make sure that each copper wire is put in the compartment where another nail is.

4. Pour vinegar into the compartments where the nails and copper wires are.

5. Put the legs of an LED bulb in vinegar: one in a compartment where only a copper wire is and the other in a compartment where only a nail is.

6. Watch the LED bulb shine in the dark. If it does not glow, reverse the legs.
