Carbon dioxide has the chemical formula CO2. This means that for every one molecule of carbon, there are two molecules of oxygen. When dissolved in water, carbon dioxide forms carbonic acid, H2CO3. Carbon acid can lose two hydrogen atoms, or protons. The loss of protons in a solution is what makes that solution acidic.
