Which acid has the largest ka. which acid has the largest . hio3(aq) hbro3(aq) hclo3(aq)  all three acids have the same ka?

dissociation of proton from the acid depends upon the central atoms's electronegativity

More is the electronegativity of halogen ⇒ more is its pull on the oxygen ⇒ easier will the bond breakage of O-H ⇒ higher the acidity

In terms of E.N :

Cl > Br > I

so HClO₃ is highest acidity with the highest Ka value

Explanation:

the answer is a I did the research
