I have a penny and a bottle of Coca-Cola. I'm wondering if the acidic content of the soda is enough to dissolve the penny over time. Will the penny completely dissolve if I leave it in the Coca-Cola?

This process is the reason why pennies appear to become shiny after being soaked in cola.

When copper oxide, commonly found on pennies, comes into contact with phosphoric acid, typically present in cola, a chemical reaction occurs.

This reaction involves the acid interacting with the copper oxide layer on the surface of the pennies.

As a result of this interaction, the copper oxide is dissolved, revealing the shiny copper metal underneath.

Besides phosphoric acid, there are other substances that could potentially be added to the cola bath.
