Weak Acid Ka Values. The equation representing the ionization of any weak acid, H

The equation representing the ionization of any weak acid, HA, and the equilibrium expression, K a, are shown below. The acid dissociation constant, denoted by Ka, is the Learn how to calculate the Ka of a weak acid from pH, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills. The pKa of a strong acid is less than zero. Ka values are good indicators of the ability to ionise. The larger the value of pKa, the smaller the extent of dissociation. SUBTOPIC: Assumptions used in weak acid pH calculations CLAS * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6th Ed. The value of Ka helps chemists and students compare the strength of different acids and is commonly used in Class 11 and Class 12 chemistry, as well as in competitive exams like JEE and NEET. Jun 16, 2024 · The following table provides p Ka and Ka values for selected weak acids. 40. Jun 10, 2025 · Our table shows Ka values for weak acids, including the Ka of acetic acid, to help you understand acid strength and dissociation in aqueous solutions.
