Question: What is the pH level of carbonic acid?

How strong is carbonic acid?

The pKa of carbonic acid was found to be 3.49 ± 0.05 using both the Marcus and Kiefer–Hynes free energy correlations. This establishes H2CO3 as being 0.37 pKa units stronger and about 1 pKa unit weaker, respectively, than the physiologically important lactic and pyruvic acids.
