Coke and vinegar can't be used together to create a battery. A Coke battery powerful enough to light an LED can be made with the soda, its can, scissors, three strips of copper, three plastic cups, four connectors and sandpaper.Continue Reading
Pour the soda into the cups, and set all three aside. Cut the aluminum can into three strips, each 1 inch wide and as tall as the can itself. If the cups are shorter than this, the strips can also be shorter.
Sand the strips of can until all the paint and plastic are completely removed from the surface on both sides.
Place one strip of sanded aluminum and one strip of copper into each cup, allowing them to protrude over the top. Do not allow the strips of metal to touch each other.
Secure both ends of the first connector to the aluminum strips in two of the cups. Attach the first end of the second connector to the copper strip in one of the cups with its aluminum strips connected. Attach the second end of the connector to the third cup. You should have one free aluminum strip and one free copper strip in a different cup.
Attach one end of your third connector to the unconnected aluminum strip and the other end to one of the LED leads. Attach one end of the final connector to the unconnected copper strip, which should be the only free strip of metal left at this point. Attach the other end of the last connector to the other LED lead. If the LED doesn't light, reverse the direction in which each connector is attached to each lead.
When combined, baking soda and vinegar release a fizzy foam, caused by the release of carbon dioxide when the two chemicals react. Baking soda, which is chemically known as sodium bicarbonate, is a basic substance, while vinegar, also known as acetic acid, is acidic. Combining the two results in a double displacement reaction in which the biproducts are water, carbon dioxide and aqueous sodium bicarbonate.Full Answer >
According to Steve Spangler Science, mixing vinegar and baking soda starts a chemical reaction that produces carbon dioxide, or CO2, and water. The chemical names of the two ingredients are acetic acid, which is the vinegar, and sodium bicarbonate, which is the baking soda.Full Answer >
Beach sand, air with clouds, oil and vinegar, granite and pizza are five examples of heterogeneous mixtures. This is because they all have components that stay separated when put together.Full Answer >
The percentage of acetic acid in vinegar refers to the unit of measurement that focuses on the strength of the vinegar. This percentage has value because it has a correlation with the safety and efficiency of its food preservation and household use.Full Answer >
