CO2 reacts with water to form hydrogen carbonate (carbonic acid), H2CO3. This molecule is a weak acid and can form HCO3(-) and CO3(2-) upon deprotonation. Keep in mind that CO2 can only form H2CO3 if there is water present, if the conditions are dry (no water present) it has no acidity at all, so neutral.
