Question

Write ionization equations and acid ionization constant expressions for each acid. (Acid ionization expressions take the general form: Equilibrium expressions take the general form: Keq = [C]c / [A]a . [B]b.. Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)

Answer 1

Consider this reaction:

H + A ---> HA

The equilibrium constant of this reaction is:

Keq = [HA]/([H][A])

For example, the acid ionization constant expression of HCl is based on this equation:

HCl ----> H+ + Cl-

Ka = ([H+][Cl-])/[HCl]
