Question

Calculate the percent dissociation of the acid in each of the following solutions.

a. 0.50 M acetic acid

b. 0.050 M acetic acid

c. 0.0050 M acetic acid

d. Use Le Châtelier’s principle to explain why percent dissociation increases as the concentration of a weak acid decrease.

e. Even though the percent dissociation increases from solutions a to c, the [H⁺] decreases. Explain.
