Nothing will happen to the penny unless kept under vinegar for a very long time.Vinegar is acetic acid but, is a weak acid.Therefore,the property of acid to liberate hydrogen when an active metal is put in it or reacted with it will also be weak. A penny made of ,say copper is not a so very active metal.Therfore it will be time taking for it to react.If it does react ,then there will be a green/blue precipitate seen in the solution,due to formation of copper acetate.
If you put a penny in distilled water, the water will not react with the copper surface of the penny. However, over time, the penny may develop a greenish-blue patina due to oxidation from exposure to oxygen in the air. This process is slow in distilled water compared to other liquids like vinegar or saltwater.
water does not react with vinegar, it just changes the color
Vinegar contains Acetic acid that reacts with the copper in the penny.
Yes, vinegar can be used to clean a penny. The acidic nature of vinegar can help dissolve and remove built-up grime and oxidation on the surface of the penny, restoring its shine. Simply soak the penny in vinegar for a few minutes, then gently scrub with a soft cloth or toothbrush to remove any remaining dirt.
Molten zinc or gallium will turn cold when you put a penny in it because they have a lower melting point than the metal in the penny, causing the penny to rapidly transfer its heat to the liquid metal and cool down.
i think the vinegar will un rist a penny
