What Will Vinegar Do to Copper?

Vinegar is a common household ingredient that can be used for cleaning, disinfecting, and cooking. But what happens when vinegar comes into contact with copper? In this article, we’ll explore the reaction between vinegar and copper and how it can be used to clean and maintain copper surfaces.

The Reaction Between Vinegar and Copper

When vinegar comes into contact with copper, it forms a chemical reaction that creates a green patina on the surface of the copper. This patina is a layer of copper acetate, which is a protective coating that helps to prevent the copper from tarnishing. The reaction between vinegar and copper is a redox reaction, which means that one substance (vinegar) is oxidized (loses electrons) while the other substance (copper) is reduced (gains electrons).

The chemical equation for the reaction between vinegar and copper is:

CH3COOH + Cu → Cu(CH3COO)2 + H2
  • CH3COOH is the chemical formula for vinegar.
  • Cu is the chemical symbol for copper.
  • Cu(CH3COO)2 is the chemical formula for copper acetate.
  • H2 is the chemical symbol for hydrogen gas.

As you can see, the reaction between vinegar and copper produces copper acetate and hydrogen gas. The hydrogen gas bubbles off as a gas, while the copper acetate forms a green patina on the surface of the copper.

How to Use Vinegar to Clean Copper

Vinegar can be used to clean copper surfaces and remove tarnish. To do this, simply mix equal parts vinegar and water in a bowl. Dip a soft cloth into the solution and wipe down the copper surface. Rinse the surface with clean water and dry it with a clean cloth.

For heavily tarnished copper, you may need to use a stronger solution of vinegar. Mix 1 part vinegar to 2 parts water in a bowl. Dip a soft cloth into the solution and wipe down the copper surface. Let the solution sit on the surface for a few minutes before rinsing it with clean water and drying it with a clean cloth.

Tips for Using Vinegar to Clean Copper

  • Always test vinegar on a small area of the copper surface before using it on the entire surface. This will help to ensure that the vinegar does not damage the copper.
  • Do not use vinegar on copper surfaces that have been coated with a clear finish. The vinegar will damage the finish.
  • Rinse the copper surface thoroughly with clean water after cleaning it with vinegar. This will help to remove any residual vinegar that could damage the copper.
  • Dry the copper surface completely with a clean cloth after cleaning it with vinegar. This will help to prevent water spots from forming on the surface.

Conclusion

Vinegar is a safe and effective way to clean copper surfaces and remove tarnish. By following the tips above, you can keep your copper looking its best for years to come.
