Carbonic acid is a weak acid that is essentially carbon dioxide. The sulfuric acid is much stronger and is a strong acid. The sulfuric acid is much more corrosive as it has a stronger pH. The carbonic acid is found in soda pop and other carbonated beverages. The pH is variable depending on its ability to join with water. Sulfuric acid is not found naturally within the environment, therefore, it would have to have a carrier molecule such as water. The only way to determine the real pH of sulfuric acid would be by dissociation, involving complex chemistry and mathematical log rhythms.
