What does asorbic acid and citric acid do to a penny?




What does ascorbic acid and citric acid this on eBay or Amazon [affil links] do to a penny?

Ascorbic acid is Vitamin C, so go to a chemists (druggist) shop and buy some, dissolve it up and drop a penny into it. citric acid can be found in citrus fruits such as lemons, limes and oranges, so get a few of these, squeeze out the juice and then drop another penny into the juice. It is by doing experiments such as this that you learn about science. It is much better to do it rather than just be told a whole string of facts, because being taught science that way makes it REALLY BORING!
