The acid-dissociation constant for hypochlorous acid (HClO) is 3.0

Explanation / Answer

.....HClO...+...H2O...<=>...H3O+...+...ClO-

I...0.0054............................0................0

C......-a...............................+a..............+a

E...0.0054-a.......................a................a


Ka of HClO = [ClO-][H3O+]/[HClO]

= a^2/(0.0054 - a) = 3.0 x 10^(-8)


a^2 + 3.0 x 10^(-8)a - 1.62 x 10^(-10) = 0


The positive root of the quadratic equation is:

a = 1.3 x 10^(-5)


(A) [H3O+] = a = 1.3 x 10^(-5) M

(B) [ClO-] = a = 1.3 x 10^(-5) M

(C) [HClO] = 0.0054 - a = 0.005387 M = 5.4 x 10^(-3) M
