Answer:
21.60% is the percent ionization of a 0.123 M solution of this acid.
Explanation:
The equilibrium reaction for dissociation of weak acidis,
initially conc. c 0 0
At eqm.
Concentration of the weak acid (c) = 0.123 M
Acid dissociation constant =
Degree of ionization of weak acid =
An expression of dissociation constant is given as:
Percent ionization of weak acid:
