The purpose of this project was to see how the reaction between a salt and vinegar solution and pennies could turn dull pennies into shiny pennies. Before starting this project I did not think a vinegar and salt solution would be able to cleanse the dull pennies but it turned out working very well. I started to become more convinced when i dipped a penny half way into it and see how clean it became.
To do this project I collected the pennies and then made the salt and vinegar solution. The salt and vinegar solution consisted of 1/4 cup of white vinegar and 1 teaspoon of salt. after making that i poured the pennies in and started noticing bubbles. i knew that the cleaning was taking effect. after about five minutes of being in the solution i took half of them out and set them aside so the solution and copper reacts with the air and creates copper oxide.
I think I had fairly decent results from this project. I definitely saw the results from the solution on the pennies and learned that even diluted acids can dissolve things off of pennies.
one thing I did well on this project was following the steps as instructed.
I did well considering i worked alone and do not know anyway i could extend this project.
