Does Coca-Cola contain acid?

Published in Daily Trivia
Coke contains citric acid (naturally occurring in fruits like lemons and limes) and phosphoric acid (found in everything from milk to fish), but in low enough concentration that the soda can’t eat a hole through your stomach lining on its own. Left in a cup overnight, Coke does not have the acidity to dissolve a penny, a nail or even a housefly.
