CO2 combines with H2O (water) in the air to make a weak acid H2CO3 (carbonic acid).

It would be acidic if you're talking about the gas coming from your mouth :P.
If you were to blow bubbles into a glass of de-ionized (distilled) water for a short time and take the pH of the water after you're finished, you would find the water is no longer neutral and slightly acidic. Just like soda which contains carbonated water, it is acidic. (Perhaps you now know why dentists have always told you to cut down on soda/pop--not just the sugary kind. Acids lead to cavities so water is the best liquid out there for you.)
