Is h2co3 a strong acid 01. Carbonic acid (H2CO3) is a weak acid. When dissolved in water, it partially ionizes into HCO3- (bicarbonate ion) and H+ (hydrogen ion). Because H2SO4 is a strong acid, we do not write an expression for the Ka. 5 H2CO3 (carbonic acid) is a weak acid. At a concentration of 10-6 mol/L or greater, the species present would be H2CO3, HCO3-, and H+. These are the reasons why carbonic acid is classified as a weak acid rather than a strong acid. HCL. Re: H2SO4 vs H2CO3 Because HSO4- has sulfur, which has a greater electronegativity than carbon, the anion is more stable (Due to electron delocalization) and thus its acid is stronger.
