Write the Ka expression for an aqueous solution of hypochlorous acid: (Note that either the numerator or denominator may contain more than one chemical species. Enter the complete numerator in the top box and the complete denominator in the bottom box. Remember to write the hydronium ion out as H3O+ , and not as H+) Ka=

Ka = [H3O+] [ClO-] / [HOCl]

Explanation:

First let us generate the dissociation equation of hypochlorous acid(HOCl) in water this given below:

HOCl + H2O <==> H3O+ + ClO-

Now we can write the Ka as follows:

Ka = [H3O+] [ClO-] /[HOCl]
