because the reaction of dissociation is At any one time virtually 100%
The acid dissociation constant (Ka) is a measure of how well an acid donates its hydrogen ions in a solution. It is the equilibrium constant for the dissociation of an acid in water into its ions. A high Ka value indicates a strong acid, while a low Ka value indicates a weak acid.
pH of the strong acid solution will be lower than the pH of the weak acid solution due to the stronger dissociation of the strong acid.
The double arrow in a dissociation equation for a weak acid represents that the reaction can occur in both the forward and reverse directions. Weak acids only partially dissociate in water, so the equilibrium can shift in either direction depending on the conditions.
Hydrochloric Acid or HCl is a strong acid. This is because it dissociates completely in water (the very definition of a strong acid/base) into H+ and Cl-. Since H+ are free in the water it causes the water to become more acidic and therefore an acid. The dissociation coupled with the free H+ after dissociation give it the classification of a strong acid.
One can determine the acid dissociation constant (Ka) of a substance without using the pH value by conducting a titration experiment. In this experiment, a known concentration of the acid is titrated with a strong base of known concentration. By measuring the volume of base required to neutralize the acid, one can calculate the Ka value using the initial concentrations of the acid and base.
The strong acid has a higher dissociation constant.

Hydroiodic Acid. It is a strong acid (100% dissociation).
According to the definition, a strong acid should dissociate completely. The second dissociation constant in sulfuric acid is nearly 95% and therefore is considered to be a strong acid.
The difference is between dissociation constants. A high value has the meaning of strong acid.
This depends on the level of dissociation of acids or bases.

Chloroacetic acid is a weak acid. Its dissociation in water is incomplete, meaning it does not completely ionize into H+ ions and its conjugate base.
One can determine the acid dissociation constant (Ka) of a substance without using the pH value by conducting a titration experiment. In this experiment, a known concentration of the acid is titrated with a strong base of known concentration. By measuring the volume of base required to neutralize the acid, one can calculate the Ka value using the initial concentrations of the acid and base.
The acid dissociation constant (Ka) for an acid dissolved in water is equal to the ratio of the concentration of the products (H+ and the conjugate base) over the concentration of the reactant (the acid). It represents the extent of dissociation of the acid in water.
