What cleans pennies better science project?
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.
What kind of juice cleans pennies best science project research?
Those tart little lemons work to remove copper oxide because they contain citric acid. Since lemon juice has the highest concentration of citric acid of any fruit, it works the best. Other juices that rank highly include lime, grapefruit, and orange juice.
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.
Which cleaning solution works best on coins?
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.
What cleans a penny best?
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.
How do you make pennies look new?
For many pennies, one tablespoon (15 g) of salt in 1/2 cup (4 oz) of vinegar will get the job done. Stir the mixture to dissolve the salt. If you don’t have vinegar, use lemon or even orange juice. Copper oxide (the gunk on your pennies ) dissolves in weak acid, and that’s just what all three of these liquids are.
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.
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.
Can ketchup clean a penny?
In order to clean the coins, we have to use a chemical reaction. The best way to do this is with an acid and salt. Ketchup contains vinegar, a weak acid, which breaks down the copper oxide on the surface of the penny. The copper chloride helps the vinegar further break down the copper oxide.
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.
How can I make my pennies shiny again?
Vinegar & Salt 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.
What do professionals use to clean coins?
Pour your distilled white vinegar into your shallow bowl. There should be enough vinegar to completely cover your coins. Gently place your coin or coins into the vinegar. Let your coins sit for at least 30 minutes.
How do you clean coins with Coke?
Simply place one coin in a glass or tub and pour coke over the top, enough so that it is fully submerged in the liquid. Leave the coin to soak for about 5 minutes or so and then check on its condition. If you feel that it needs longer, you can soak it for up to 15 minutes.
How do you clean dirty coins without vinegar?
Place the coins in a solution of dish soap and water.
- If you have a particularly dirty coin, you can allow it to soak in the solution.
- A non-abrasive liquid solvent like distilled water and a weak soap will have enough cleaning power to clean your coins, and does not contain acids that can corrode them.
