The acid dissociation constant is a value that is essential to understanding basic reactions in chemistry. These values represent the deprotonation state of a molecule in a solvent medium. Based on the value of dissociation constant (Ka), we can investigate the important properties such as the bio-activity, the absorbance and ionization degree of organic compounds at different environments. Therefore, the determination of dissociation constant plays an important role in the study of chemical processes. This work present a simple method to determine the dissociation constant based on conductivity measurement. Acetic acid is objective for this study. The obtained value of dissociation constant for acetic acid is to 1.79*10-5, which is perfectly matches the actual value. Therefore, this method can be very effective way for determining the Ka values of other acids, especially acids of unknown name.
