Why does vinegar have such a strong chemical reaction when in contact with copper?
Vinegar, which contains acetic acid, reacts with copper due to the acid's ability to dissolve copper oxide and other copper compounds. This reaction leads to the formation of copper acetate, which can result in the release of hydrogen gas and a visible effervescence. The strong reaction is a result of the acid's corrosive nature on the metal, particularly when the copper is oxidized. This interaction can cause the copper to tarnish or change color as it reacts with the acid.

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.
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.
What is the chemical reaction for rusting copper?
2Cu+H2O+CO2+O2=Cu(OH)2.CuCo3
Who invented how to clean a penny with vinegar?
The process of using vinegar to clean a penny is a common science experiment that demonstrates the chemical reaction between the acid in vinegar and the tarnish on the surface of the penny. There is no specific person who can be credited with "inventing" this method, as it is a simple and well-known technique in the realm of science education.
Is it true copper lost matter?
Without a chemical reaction copper remain copper.
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.
Is there a reaction between iron and copper sulfate?
Yes, when iron comes into contact with copper sulfate, a chemical reaction occurs where the iron displaces the copper in the compound, forming iron sulfate and copper. This reaction is known as a displacement reaction.
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.
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.
Is it a chemical reaction when salt and vinegar clean the bottom of a copper pot?
Yes, the combination of salt and vinegar on the copper pot creates a chemical reaction that helps remove tarnish and dirt from the surface. The salt acts as an abrasive while the vinegar reacts with the tarnish to help dissolve it, making it easier to clean the pot.
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.
Does copper carbonate react to vinegar?
Yes, copper carbonate reacts with vinegar, which is an acetic acid solution. When they come into contact, the acetic acid reacts with the copper carbonate to produce copper acetate, water, and carbon dioxide gas. This reaction may be observed as bubbling or fizzing due to the release of carbon dioxide.
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.
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.
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.
What type of chemical reaction is copper chloride?
Copper chloride is not a chemical reaction, it is an ionic compound.
