How can copper be oxidized using vinegar?
Copper can be oxidized using vinegar through a chemical reaction that occurs when the copper comes into contact with the acetic acid in the vinegar. This reaction causes the copper to lose electrons, resulting in the formation of copper oxide on the surface of the copper.
What metal goes green in vinegar?
Copper metal turns green when exposed to vinegar due to a chemical reaction that forms copper acetate. This green substance is known as verdigris and is a common patina that forms on copper surfaces exposed to acidic environments.
What causes vinegar to rust a penny?
Pennies are made of zinc plated with copper. Copper reacts with oxygen and water to form copper oxide. This is the tarnish you see on pennies that have been in damp conditions. The only U.S. coins that can truly rust are the 1943 zinc coated steel cents.
How can one create patina on copper?
To create patina on copper, you can expose the copper to elements like water, salt, vinegar, or ammonia. This will cause a chemical reaction that forms a greenish-blue layer on the surface of the copper, giving it a weathered and aged appearance.
Is dissolution of a copper penny in nitric acid a chemical reaction?
Yes. Dissolution of a copper penny would indeed be a chemical reaction.

Is cleaning a penny with vinegar and salt a physical or chemical change?
Cleaning a penny with vinegar and salt is a chemical change. The vinegar (acetic acid) reacts with the salt (sodium chloride) to form a chemical compound that removes the tarnish on the copper surface of the penny. This reaction changes the composition of the penny's surface, making it appear shiny and clean.

How can you tell that a chemical reaction occurred from the copper sulfate?
You can tell that a chemical reaction occurred with copper sulfate if there is a visible color change in the solution, such as the solution turning blue or green. Additionally, if there is a formation of a solid precipitate, like copper hydroxide forming as a blue-green solid at the bottom of the solution, it indicates a chemical reaction has taken place.

Is dissolution of a copper penny in nitric acid a chemical reaction?
Yes. Dissolution of a copper penny would indeed be a chemical reaction.
Is the reactivity of copper with oxygen considered a chemical or physical property?
The correct spelling is "reaction of copper with...' 1. Chemical reactivity is a chemical property. 2. A chemical reaction involve a chemical change.
How can I oxidize copper to achieve a green patina?
To oxidize copper and achieve a green patina, you can expose the copper to a combination of oxygen, moisture, and acidic substances like vinegar or saltwater. This process will create a chemical reaction that forms the green patina on the copper surface.
What is the chemical reaction for rusting copper?
2Cu+H2O+CO2+O2=Cu(OH)2.CuCo3
What type of chemical reaction is copper chloride?
Copper chloride is not a chemical reaction, it is an ionic compound.
Is it true copper lost matter?
Without a chemical reaction copper remain copper.
