How long does it take for a penny to rust?<\/strong> Technically, the penny doesn’t rust, the copper plating on its surface only corrodes which results in a green surface tarnish. The corrosion occurs due to the chemical reaction that occurs between the metal, moisture or water, oxygen, and CO2 (carbon dioxide) in the air.<\/p>\n The common green color known as ‘green patina’ seen on old pennies can take up to twenty years to form if it is not dipped in an extra solution. Because a penny cannot rust, this article has explained corrosion on a penny, why and what makes a penny to corrode, how to tarnish a penny yourself, what can fasten the process, and how to clean a penny that has undergone corrosion.<\/strong><\/p>\n Keep reading!<\/p>\n Contents<\/p> Looking at a penny, you will see that it looks like copper, but it’s a combination of a few metals like tin, steel, copper, zinc, or nickel unless it’s an old piece of a penny. Even if a penny has a mixture of these other metals, the outer coating is almost always copper, and exposing it to the atmosphere will make it corrode.<\/p>\n <\/p>\n The pennies that contain a high amount of zinc will not corrode because of their high resistance to atmospheric corrosion.<\/p>\n Pennies change color due to corrosion. Copper, which is a significant component of a penny, tends to corrode when exposed to sulfur or oxygen, even though it has a high level of resistance.<\/p>\n This means that even the oxygen we breathe in every day can corrode a penny when the oxygen molecules react with the copper in a chemical process called oxidation. After the oxidation reaction, a layer of green film will be seen on the surface of the penny signifying that corrosion has taken place.<\/p>\n <\/p>\n This green film deposited on the surface of the penny is sometimes known as patina and its scientific name is known as ‘copper hydroxide carbonate.’<\/p>\n Cleaning dull or corroded pennies isn’t difficult. Simply dip them into a solution of salt, water, and vinegar. While the acetic acid in the vinegar dissolves copper oxides, the salt will speed up the rate of the reaction.<\/p>\n You can also use lemon juice that contains citric acid to clean corroded pennies, and cleaned corroded pennies normally turn bright again within a few seconds.<\/p>\nWhy Does A Penny Corrode?<\/span><\/h2>\n
