Question

Arrange the following oxyacids of chlorine w.r.t. increasing order of their acidic strength
Chlorous acid , perchloric acid , chloric acid , hypochlorous acid.​

Answer 1

Oxyacids of chlorine with reference to the increasing order of their acidic strength:

(Weakest)

Hypochlorous acid  HClO

Chlorous acid HClO$_{2}$

Chloric acid HClO$_{3}$

Perchloric acid HClO$_{4}$

 

(Strongest)

The common measure of the strength of an acid is its acid dissociation constant (Ka).  Larger Ka means stronger acid while smaller Ka weaker acids. For oxoacids, pKa values decrease with the oxidation state of the element.
