Question:
Hypochlorous acid (HOCl) has an ionization constant of 3.2 x 10-8. What is its percent ionization in 1.0 M and 0.10 M solutions, respectively?
Ionization constant for acids and bases:
The ionization, or dissociation, constant, (Ka) is the likelihood of an acid to lose a proton to yield its constituent ions in solution. The smaller the value of the dissociation constant, the less the acid dissociates. This is because reactants are favored when K is less than 1. Bases have what is referred to as a hydrolysis constant (Kb). This constant refers to the likelihood of a base to accept a proton. Similar to acids, the smaller the base hydrolysis constant, the less the base accepts a proton.

Chapter 11 / Lesson 22In this lesson we will describe the acid ionization constant. Using basic equations we will calculate the constant first. Next we use it to compare the relative strengths of different acids. Also, we cover how to calculate the constant for acids that have multiple protons that could be lost in a solution.
