What cleans a penny better science fair 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.
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.
Does water or vinegar clean a penny better experiment?
The “dirt” on the pennies was a new chemical substance called copper oxide. It doesn’t easily come off, as you found out by trying to scrub them with plain water. When you mix the salt and vinegar, however, this makes a new substance, too; a type of acid. This acid is really good at breaking down the dirty pennies.
What solution cleans coins the best?
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 dirty coins fast?
Take the coins out and sprinkle some baking soda over them; then use a soft-bristled toothbrush to brush them clean. Rinse them out thoroughly with hot water; using tongs or gloves to hold them to avoid burning your fingers. Place them on a soft, cotton towel and leave to air dry.
Why does lemon juice make pennies shiny?
THE SCIENCE BEHIND IT Vinegar and lemon juice are acidic and will remove the copper oxide, leaving the pennies shiny.
Why do pennies get clean in vinegar?
When you put your dirty pennies in the vinegar and salt, the copper oxide and some of the copper dissolve in the water. That means some copper atoms leave the penny and start floating around in the liquid. So you’ve got positively charged iron ions floating in your vinegar with the positively charged copper ions.
How do you clean a penny without damaging the value?
Vinegar. A common ingredient in DIY eco-friendly cleaners, the acetic acid in white vinegar can help wear away the contamination on your coins. Soak your coins in a glass or other non-corrosive container for at least 30 minutes, up to overnight, and then wipe with a clean cloth or scrub gently with an old toothbrush.
Why do pennies turn dull?
When oxygen binds with copper, they form a new molecule known as copper oxide. This is why most pennies you see look dirty or tarnished—it’s not actually dirt but copper oxide that makes them look so dull.
Can Coke dissolve a penny?
Theoretically, yes, it will dissolve a penny, if you left it in for YEARS, and kept replenishing the Coke with fresh Coke. PENNIES ARE MADE OF COPPER, WHICH WILL DISSOLVE IN THE PRESENCE OF ACID, ONE OF THE MAIN INGREDIENTS IN ALL SODA IS PHOSPHORIC ACID. THE pH of soda is quite low, due to the phosphoric acid content.
Can ketchup clean a penny?
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. Hot sauce, like Tabasco or taco sauce, also will remove the oxides off pennies.
Can vinegar damage coins?
Copper. Distilled white vinegar, that housecleaning standard, will strip away the tarnish or patina that copper coins acquire with time and use. Mix half a cup of vinegar with a teaspoon of salt and drop in the pennies. They will lose their dullness and brown color and look newly minted very quickly.
Are wheat pennies worth anything?
Most wheat cents (wheat pennies were minted between 1909 and 1956) are worth about 4 to 5 cents. Those in better condition can have double-digit value. Special examples (especially those in near perfect condition) can be worth much more. Indian Head pennies from 1859 to 1879 are generally worth more than $10.
Can you clean pennies with toothpaste?
Don’t use toothpaste – Toothpaste is extremely abrasive. It can make your coins appear shiny, but cause significant damage to the surface. Don’t use vinegar and baking soda – When put together, these two common household items create a potent, fizzy mixture that can clean dirt from coins.
