Use this acids and bases chart to find the relative strength of the most common acids and bases. This acid-base chart includes the K a value for reference along with the chemical's formula and the acid’s conjugate base.
Strong bases completely dissociate in aq solution (Kb > 1, pKb < 1). Conjugate acids (cations) of strong bases are ineffective bases. * 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.
Table of Contents. pka and Acidity; pKa Table; Frequently Asked Questions – FAQs; pka and Acidity. The molecular structures of acids and bases have a direct impact on pH and pKa values. Chemists can also use pKa to determine acidity that isn’t dependent on the amount of acid present.

While Table \(\PageIndex{1}\) provides the pK a values of only a limited number of compounds, it can be very useful as a starting point for estimating the acidity or basicity of just about any organic molecule. Here is where your familiarity with organic functional groups will come in very handy.
16 gru 2021 · The approximate ranges of pK a values for seven major functional groups are listed in Table 3.1, which serves as a very valuable starting point for us to predict and understand the acidity of any organic molecule.
