Interpretation: The acid dissociation constant is to be calculated.
Concept introduction: The ratio of the concentration of the ionized form of an acid to the concentration of the unionized form of the acid is known as the dissociation constant or ionization constant. It is denoted as
The dissociation constant Ka of the acid HA is written as:
