Answer : The expression for acid dissociation constant will be:
[tex]K_a=\frac{[H^+][H_2BO_3^-]}{[H_3BO_3]}[/tex]
Explanation :
Acid dissociation constant : It is an equilibrium constant that refers to the dissociation or ionization of an acid.
It is denoted as [tex]K_a[/tex].
The given equilibrium reaction is:
[tex]H_3BO_3(aq)\rightleftharpoons H^+(aq)+H_2BO_3^-(aq)[/tex]
The expression for acid dissociation constant will be:
[tex]K_a=\frac{[H^+][H_2BO_3^-]}{[H_3BO_3]}[/tex]
