What type of acid does Coke contain?
Coke, (the soda, I'm assuming) contains Citric acid, which is
mostly harmless and will not devour a penny in 3 hours, or
magically obliterate mineral deposits or chew through concrete or
anything. If you're an excessive drinker though, it can inflict
damage on the enamel of your teeth. To avoid that unpleasantness,
you can use a straw or just... drink.. less.
Unfortunately Tricia, your answer leaves quite a bit to be
Citric acid may be harmless but Phosphoric acid, which is the
main acid used in coke (primarily because its far cheaper than
citric acid) has big shadows hanging over its safety. Various
studies have been conducted which initially showed that this stuff
had a detrimental effect on bone density (amongst other things)
Unsurprisingly, soon after this came out, another study was done,
probably commissioned and controlled by the manufacturers which
showed it was (lo and behold) actually good for the bones. Which
all just goes to that you can get whatever test results you want if
you know how to manipulate the results.
