See explanation.

Explanation:

Acids have the general formula H_xAHxA which means that they have to possess one hydrogen atom at least, which is not the case of carbon dioxide CO_2CO2.

However, CO_2CO2 when it dissolved in water it forms the carbonic acid:

CO_2(g) + H_2O(l)rightleftharpoonsH_2CO_3(aq)CO2(g)+H2O(l)H2CO3(aq)
