Answer:
Ka = [H3O+] [N3-] /[HN3]
Step-by-step explanation:
We'll begin by writing the ionization equation for HN3. This is illustrated below:
When HN3 ionizes in water, the following are obtained:
HN3 + H2O <==> H3O+ + N3-
The ionization constant, Ka is simply the ratio of the concentration of the products to that of the reactants.
Thus, the ionization constant, Ka for HN3 it written as follow:
Ka = [H3O+] [N3-] /[HN3]
