Answer:

[tex]HClO_{2}[/tex] is the strongest acid

Explanation:

[tex]K_{a}[/tex] of an acid represents acid dissociation constant.

For an acid HA: [tex]HA\rightleftharpoons H^{+}+A^{-}[/tex]

                            [tex]K_{a}=\frac{[H^{+}][A^{-}]}{[HA]}[/tex]

Therefore more the value of [tex]K_{a}[/tex] , more will be degree of dissociation of acid. Hence stronger will be the acid.

Among the all five acids, [tex]HClO_{2}[/tex] has highest  [tex]K_{a}[/tex] value. Therefore it represents, at equilibrium, [tex]HClO_{2}[/tex] has highest degree of dissociation.

Hence [tex]HClO_{2}[/tex] is the strongest acid
