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.

Which liquid will rust a penny faster vinigar or salt water?

Salt water will rust a penny faster than vinegar because salt water is an electrolyte that enhances the electrical conductivity, accelerating the oxidation process on the surface of the penny.


Which liquid rusts a penny fastest?

Vinegar is known to rust a penny the fastest due to its acidic nature, which accelerates the oxidation process on the coin's surface. Placing a penny in vinegar for a short period of time will result in visible signs of rust forming.


What acids can make a rusty penny a shiny penny?

Common household acids like vinegar (acetic acid) can be used to remove rust from a penny, making it shiny again. The acid reacts with the rust (iron oxide) on the penny's surface, dissolving it and revealing the shiny metal beneath. It is important to note that strong acids or chemical solutions should be handled with care and proper safety precautions.


What happens during the rust vinegar reaction and how does it affect the metal surface?

During the rust vinegar reaction, the acetic acid in vinegar reacts with the iron in the metal to form iron acetate and hydrogen gas. This reaction causes the metal surface to corrode and form rust, which is a reddish-brown compound that weakens the metal and can eventually lead to its deterioration.


What effect does vinegar have on rust?

Vinegar can help remove rust by breaking down the iron oxide that forms rust. The acetic acid in vinegar reacts with the rust, making it easier to scrub off the metal surface.
