Pennies cleaning Science experiment conclusion

Conclusion Which solution will clean copper pennies the best, soap and water, lemon juice, vinegar and salt, coca cola, or ketchup? If I put a copper penny in soap and water, lemon juice, vinegar.. Cleaning Pennies Science Experiment Explained Pennies turn dull and green due to oxidation. Over time, pennies form a layer of copper oxide on the surface of the penny, which actually protects it from further corruption

Conclusion: The hypothesis was proven true, and the pennies, were best cleaned by the strongest acid, which in this experiment was lemon juice. A questionable aspect of this experiment is arisen with the change of the color of ammonia during the experiment Vinegar and lemon juice both work really well for cleaning pennies. But, ketchup was the clear winners for our pennies, with soy sauce next, maybe with a little more time they would have gotten a little bit cleaner. This is a fun experiment to try with younger kids! My kids of all ages were interested in the results, though I believe that the vinegar and salt will clean the pennies better compared to the other solutions because vinegar mixed with salt creates an acid that can clean what is called copper oxide which in other words is the rust on the penny Complete the experiment using the same procedures but leave a couple of pennies in the vinegar and in the soapy water solutions for an hour or more. Come back and see how the pennies have changed. Try cleaning some pennies minted before 1982 and some that were minted after, and see the difference

Ketchup Soak your pennies in ketchup to clean them like new. Well, after you wash the ketchup off, that is. The salt and acetic acid in vinegar do the trick In a scale from one to ten based on the reactions and changes that pennies had, I gave it a score of 8 to pennies inserted in vinegar and salt and a 1 to pennies with water. I do not gave a 10 to salt and vinegar because at the end the pennies were not totally cleaned. The dirty was cleaned a lot but not completely So when the coin stays in your pocket or is passed from person to person or stays in that container where you keep all your pennies, the copper in the coin reacts with the oxygen in the air and turns into what is called copper oxide. Copper oxide is blackish. It's that dull dark color that coats old coins

The unlikely condiment you need to be sure to include? Ketchup. Trust me on this. Your kids will love this simple chemistry experiment. It is a great sensory STEM activity for preschoolers and older children. Here is the science of cleaning pennies with. The pennies looked dull and dirty because they were covered with copper oxide. Why did the vinegar and salt clean the pennies? Copper oxide dissolves in a mixture of weak acid and table salt-and vinegar is an acid. You could also clean your pennies with salt and lemon juice or orange juice, because those juices are acids, too

Pennies become dull over time as copper on the surface reacts with oxygen from the air. The two elements combine to form dark chemicals called copper oxides. The acetic acid in vinegar dissolves these chemicals and leaves the copper surface of the penny looking shiny. Soap can clean lots of things, but it can't dissolve copper oxides Try this Cleaning Pennies experiment to find out if a rusty penny can become shiny with the help of salt and vinegar! Great for kindergarten, first grade, and second grade science projects Oxygen in the air combines with the copper in the penny to form copper oxide, which makes the penny look dull and dingy. You can make the pennies look like new again by soaking them in water that is corrosive enough to strip off the copper oxide layer
