What is the pKa value of carbonic acid?

Chapter 27 Appendix C: Dissociation Constants and pK a Values for Acids at 25°C Name Formula pK a1 Benzoic acid C 6H 5CO 2H 4.204 Boric acid H 3BO 3 9.27* Bromoacetic acid CH 2BrCO 2H 2.90 Carbonic acid H 2CO 3 6.35 Click to see full answer. Correspondingly, what is the pKa of carbonic acid?At 298 K, the experimental pKa1 and pKa2 for carbonic acid is 6.36, 10.33 separately and the experimental pKa for formic acid is 3.75 [17]. In addition, the more visual comparison between the calculated and experimental pKa of carbonic acid and formic acid at B3LYP/6-311++G(d, p) level is presented in Fig.Beside above, what is the pKa value? Key Takeaways: pKa Definition The pKa value is one method used to indicate the strength of an acid. pKa is the negative log of the acid dissociation constant or Ka value. A lower pKa value indicates a stronger acid. That is, the lower value indicates the acid more fully dissociates in water. Keeping this in consideration, what is the Ka value of propionic acid? Solution: The Ka of propanoic acid (C2H5COOH) is 1.34 × 10-5.What is the pH level of carbonic acid? pH of Common Acids and Bases Acid Name 1 mM HAcetate acetic acid, C2H4O2 (ethanoic acid) 3.91 H2CO3 carbonic acid 4.68 H2S hydrogen sulfide 4.97 H3AsO3 arsenious acid 6.07
