What happens when you mix copper and vinegar?
When you wash old copper pennies with vinegar, the pennies react with the vinegar to form a blue compound called copper (II) acetate. Now, if you let that vinegar dry, small, black crystals will be left behind in the dish. Those are copper acetate crystals. It turns out you can grow much bigger copper acetate crystals.
In Bowl 1, the vinegar helps speed up a chemical reaction between the copper in the penny and the oxygen in the air. This reaction is called oxidation. When copper oxidizes, it turns a blue-green color, forming a compound called malachite. In Bowl 2, the vinegar and salt create a chemical reaction.
The process begins with making a saturated solution of copper acetate by dissolving the scrap copper bits in the vinegar and peroxide for a couple of days. The solution is concentrated by evaporation until copper acetate crystals start to form.
Generally, pure copper does not react with acetic acid; however, a reactive oxide layer is formed upon exposure to air.
Actually, there is little to no reaction of vinegar on copper metal (hence, the copper wire in solution is clear). Existing Cu2O coating will be slowly attacked, forming a cuprous acetate which in air/oxygen creates soluble cupric acetate.
Soaking copper in white vinegar and salt will create a blue or green patina. Other ways of doing this are to bury the copper in sawdust or crushed potato chips soaked in white vinegar. The longer the copper is buried, the darker the patina becomes.
The acid in the vinegar will clean copper, some have flour or other ingredients to make a paste to keep the acid on the copper. Ketchup and Lemon juice are also acids and will clean copper and brass.
Grow beautiful white Aragonite crystals. Sometimes called "Popcorn Rocks", these gray Dolomite samples grow dazzling, white Aragonite crystals when placed in a small amount of white vinegar. This experiment is a must for any classroom studying rocks, minerals, crystals, or geology.
Most harsh substances are capable of oxidizing copper, but you don't need to buy special acids just for that. Basic products like vinegar and salt can have the same effect. All you need is enough amount of these products to submerge your copper item for a certain period.

Does hydrogen peroxide react with copper?
The rate of dissolution of copper in hydrogen peroxide solution goes through a maximum then drops at higher peroxide concentrations. A similar behavior has been observed in copper CMP, where the rate of polishing exhibits a peak and then decreases as the oxidizer concentration further increases.
Copper does not react with salt water.
Copper is one of the least resistant metals to salt-related corrosion. Over time, copper pipes will turn bluish-green with exposure and eventually crumble away. Galvanized steel and cast iron are more resistant to saltwater corrosion, but exposure over time can still cause damage.
When an acid reacts with base it forms salt. Vinegar is acetic acid CH 3 COOH and simple salt is sodium chloride . The reaction between acid and the salt takes place as follows: Hence from the above reaction, we can say that when vinegar reacts with salt hydrochloric acid is produced.
When oxygen binds with copper, they form a new molecule known as copper oxide. Copper oxide is brownish or sometimes black in color (depending on other things in the penny's environment). 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.
Vinegar is an acid and if placed in metal goblets, even for a short time will begin to dissolve many metals. Lead, copper and aluminum, iron are common examples. While the body needs iron, it can do without most other metals that dissolve in vinegar.
Add enough white vinegar to cover your metal. Give the bucket a light shake, and let your bucket stand for about 20 minutes. Remove your metal and dry (inside and out) with a Bounty Paper Towels.
Bury copper in white vinegar.
Place in a sealed container for 2–8 hours, checking on the color regularly, then remove and air dry.
If you have a bottle of co*ke in your house this can be a handy method to clean copper. For items like jewelry that are small and can be soaked, consider using this method. co*ke is also a great option when wanting to know how to clean copper pans and pots that you can soak in the sink.
Does WD 40 clean copper? WD 40 won't clean tarnished copper, but it may be able to act as a sealant (along with carnauba wax or mineral oil) to prevent future tarnishing.
What does Windex do to copper?
Copper. “The alcohol contained in Windex will affect the patina of the copper and could cause permanent discoloration,” shares Sarah Steeb, a home cleaning expert with Housekeeping Associates. Instead, use water on those copper pots, pans, trays, etc. and buff it out with a microfiber cloth, she says.
Vinegar, an acid, dissolves bits of a material called calcium carbonate in the limestone. This releases carbon dioxide, a gas that rises to the surface as a stream of bubbles. Rocks that don't contain calcium carbonate won't fizz.
Vinegar is an acidic solution with a pH level of around 2.5, which can etch and dull the surface of your quartz countertops. Over time, repeated use of vinegar can cause damage and compromise the integrity of your countertops.
As the solution cools, the magnesium sulfate atoms run into each other and join together in a crystal structure. Crystals grown this way will be small, thin, and numerous. Left undisturbed, the crystals should last months or more!
Place the copper in a glass container and add a generous layer of coarse salt. Add a few drops of ammonia and a few drops of vinegar over the salt. Just a few drops so that the salt is barely wet. Cover (but don't completely seal) the container with plastic wrap.
