We will try to coat coins in green colour in this experiment by using no colour at all. You don’t seem to believe, do you? Check out yourself.
Things Required:
Saucer
Paper towel section
Vinegar 3-5
Coins (Copper)
Directions:
Fold the paper towel in half; fold again to form a square. Place the folded towel in the saucer.
Pour enough vinegar into the saucer to wet the towel. Place the copper coins on top of the wet paper towel. Wait for 24 hours.
Science Behind It:
The chemical name of vinegar is acetic acid. The acetate part of the acid combines with the copper on the coins to form the green coating composed of copper acetate.
