Take a glass of still water and a glass of sparkling water, and let it sit overnight. The sparkling water should have gone flat by then. Now taste them. Do they taste the same?

Nope! The dissolved carbon dioxide takes a very long time to actually dissipate, and so there might still be some left over. But even still, there should be some carbonic acid left over from the CO2 molecules reacting with the H2O to make H2CO3, making the water very slightly acidic.
