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 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.
TABLE OF CONJUGATE ACID-BASE PAIRS Acid Base K a (25 oC) HClO 4 ClO 4 – H 2 SO 4 HSO 4 – HCl Cl– HNO 3 NO 3 – H 3 O + H 2 O H 2 CrO 4 HCrO 4 – 1.8 x 10–1 H 2 C 2 O 4 (oxalic acid) HC 2 O 4 – 5.90 x 10–2 [H 2 SO 3] = SO 2 (aq) + H2 O HSO
14 sie 2020 · To know the relationship between acid or base strength and the magnitude of Ka, Kb, pKa, and pKb. To understand the leveling effect. The magnitude of the equilibrium constant for an ionization reaction can be used to determine the relative strengths of acids and bases.
1. Strong acids are listed at the top left hand corner of the table and have Ka values >1 2. Acid with values less than one are considered weak. 3. The strong bases are listed at the bottom right of the table and get weaker as we move to the top of the table.
This document lists the dissociation constants (Ka or Kb values) for various acids and bases at 25 degrees Celsius. For acids, it provides the first, second, and third dissociation constants where applicable.
Figure 1 is a titration curve for the titration of HCl by NaOH, a strong acid and strong base, where 25.0 mL of 0.1 M HCl is titrated with 0.1 M NaOH. NaOH titration of HCl
