Science Projects on Cleaning a Penny
- Ketchup. Soak your pennies in ketchup to clean them like new.
- Hot Sauce. Hot sauce, like Tabasco or taco sauce, also will remove the oxides off pennies.
- Coke. Coke and off-brand colas will quickly remove the tarnish.
- Citrus Juice.
- Pencil Eraser.
- Vinegar and Salt.
What liquid cleans copper pennies the best?
Vinegar (or Lemon Juice) and Salt This method is the best way to clean your pennies, and it will produce a very bright orangey-copper color on your pennies. It does this by using the low levels of acids that are contained naturally in vinegar and lemon juice to remove the patina (brown oxidation) on the penny.
What liquid will react with a penny the most?
Which Liquids Will Tarnish a Penny Faster?
- Potassium Sulfide. Potassium sulfide dissolved in water creates a solution that puts tarnish on a penny.
- Bleach. Bleach will also tarnish pennies.
- Vinegar. Acid speeds up the oxidation process taking place on copper.
- Liver of Sulphur. Liver of sulphur will also create a tarnish on any copper surface, including pennies.
What is the best way to clean 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.
What cleans a penny better experiment?
Create a solution of vinegar and salt using one teaspoon of salt and 1/4 of a cup of vinegar. Mix until the salt is dissolved (it helps if the vinegar is a little warm). Add the pennies. Wait about 5 minutes, then remove the pennies from the solution.
Why do pennies turn green?
A chemical reaction has occurred! (A chemical reaction is the combination of two reactants to form something entirely new.) A penny is made of copper. The vinegar on the paper towel helps the copper in the penny easily react with the oxygen in the air to form a blue- green colored compound called malachite.
Does Coke really clean coins?
Coke and off-brand colas will quickly remove the tarnish. Just don’t drink the coke afterward. Coke contains phosphoric acid that cleans the oxides. Try a variety of citrus juices to see which works best or simply let your pennies soak in lemon juice.
Does lemon juice clean pennies better than vinegar?
Ultimately, lemon juice will clean pennies better than vinegar, though both liquids are viable cleaning options for copper. This means that lemon juice is a slightly stronger acid than vinegar. The stronger the acid, the better it will clean copper pennies.
How do you clean a coin without damaging it?
Follow These Steps:
- In a jar, combine one cup vinegar (or lemon juice) and 1 tablespoon salt.
- Pour the solution into the plastic container.
- Add the coins in a single layer, so none of the coins are touching.
- When you remove the coins and wipe them with a cloth or paper towel, they should look shiny.
How do you clean copper that has turned black?
Lemon juice and salt are useful for removing tarnish from copper in three easy steps:
- Squeeze the juice of the lemon in a bowl and then sprinkle the salt into the juice.
- Stir for a minute until the salt dissolves.
- Dip a cloth into the solution and wipe the copper.
Does vinegar and salt make hydrochloric acid?
When vinegar is mixed with salt, the acetic acid in the vinegar reacts with the sodium chloride or salt to produce sodium acetate and hydrochloric acid. The hydrochloric acid is a strong acid.
Why do pennies lose their shine?
All pennies start out the same color—bright copper. But somewhere along the way, those pennies lose their luster. The negatively charged oxygen atoms in our air are attracted to the positively charged copper atoms in the penny. When oxygen binds with copper, they form a new molecule known as copper oxide.
Can vinegar damage coins?
Just be sure to rinse off the vinegar with water after you’ve soaked them, since any remaining vinegar residue could cause the coins to oxidize again. First, if you think your coins might be of any value, do not clean them at all, since you can possibly damage them by soaking in cleaners like vinegar.
How do you clean pennies without losing their value?
The use of vinegar and salt to clean pennies goes way back. It works on the same principle as using ketchup (Ketchup contains vinegar, salt and tomatoes), but there is less rubbing involved. Mix up a concoction of vinegar and salt. Stir it around to dissolve the salt and then dump in your dirty pennies.
Does rubbing alcohol clean pennies?
To soak your coins, you will create a bath using isopropyl alcohol and salt. It is important to note that each of these chemicals is acidic and abrasive. While they will do a great job of cleaning your coins, be careful of how many contacts they have with your skin.
