Vinegar contains Acetic acid that reacts with the copper in the penny.
Vinegar is a weak acid. If I remember my chemistry lessons of 40+ years ago correctly the action of an acid on a dirty penny should produce some sort of salty substance and water and the penny will then appear clean.
The vinegar and salt in the ketchup will remove most of the dark tarnish on a darkened or dirty copper penny (you can accomplish the same effect more quickly using just a small dish of vinegar and salt). However, the penny will "clean up" with a slightly beige-pink or rosy color, significantly not quite the color of a shiny new penny.
Mix a tablespoon of vinegar with a pinch of salt in a small bowl. Dip the penny in the mixture and rub gently with a cloth or your fingers to remove the dirt and grime. Rinse the penny with water and dry it with a soft cloth.
Yes.
Vinegar, ketchup, lemon juice, and baking soda are substances that can effectively clean a dirty penny. Each of these substances contains acids or other compounds that can help break down the dirt and grime on the surface of the penny, restoring its shine.
vinegar has an acid in it that dissolves microscopic particles only found on certain matals.
If you have any tarnished pennies in your penny jar, you can easily clean them in vinegar. If you leave your pennies in white vinegar and salt for about 30 minutes and they will come out shiny and pretty clean. Be sure to rinse the vinegar off.
yes because all of the chemicals in the sodas can make a compound to clean the dirty penny!
Vinegar is acid.. Soda is sugar and carbonation.
When vinegar and salt are combined to clean pennies, a chemical reaction occurs that removes the tarnish on the coins. The acidic vinegar breaks down the tarnish while the salt acts as a mild abrasive to help scrub away the debris. This process can restore the shine and luster of the pennies.
the acidity breaks into the dirty molecules and cleans it off
