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.
Bleach can clean a penny in a few seconds to a few minutes, depending on the concentration of the bleach and the level of oxidation on the penny's surface. It is important to monitor the cleaning process closely to avoid overexposure, which can damage the penny.
Cleaning a penny can take just a few seconds to a few minutes depending on the method used. Using a combination of vinegar and salt can quickly remove tarnish and dirt from the surface of the penny. Rubbing the penny with a cloth or soft-bristled brush can help speed up the cleaning process.
