When a aqueous solution of a certain acid is prepared, the acid is dissociated. Calculate the acid dissociation constant of the acid. Round your answer to significant digits.

=

Explanation:

When an aqueous solution of a certain acid is prepared it is dissociated is as follows-

         ⇄  

Here HA is a protonic acid such as acetic acid,

The double arrow signifies that it is an equilibrium process, which means the dissociation and recombination of the acid occur simultaneously.The acid dissociation constant can be given by -

        =

The reaction is can also be represented by Bronsted and lowry -

          ⇄  

Then the dissociation constant will be

        =

Here, is the dissociation constant of an acid.
