Table of Acids with Ka and pKa Values* CLAS * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6th Ed. The pKa values for organic acids can be found in Appendix II of Bruice 5th Ed.

This is “Appendix C: Dissociation Constants and pKa Values for Acids at 25°C”, appendix 3 from the book Principles of General Chemistry (v. 1.0). For details on it (including licensing), click here .

The acid dissociation constant for an acid is a direct consequence of the underlying thermodynamics of the dissociation reaction; the pK a value is directly proportional to the standard Gibbs free energy change for the reaction.

This acid-base chart includes the K a value for reference along with the chemical's formula and the acid’s conjugate base. The acid and base chart is a reference table designed to make determining the strength of acids and bases simpler.

The key idea to remember is this: the stronger the conjugate acid, the weaker the conjugate base. Sulfuric acid is the strongest acid on our list with a pK a value of –10, so HSO 4-is the weakest conjugate base.

This pKa calculator helps you find the pKa from pH with the Henderson-Hasselbalch equation or with acid dissociation constant (Ka) values.

Aug 30, 2023 · How to use a pKa Table. pKa values have been recorded for a vast variety of compounds and are mainly connected to the molecule’s most acidic functional group. A pKa table simplifies pKa values. A low pKa value (for example, -10) implies a strong acid. A high pKa value (for example, 50) implies a weak acid.

Based on the K a values, HCl is the strongest acid followed by HNO 2, and then CH 3 CO 2 H. HCl has the smallest pKa, while the weakest among these, the acetic acid has the largest pK a value. So, remember this trait – stronger acids have lower p K a.
