Question 12 (1 point)

Which of the following could be added to an aqueous solution of weak acid HF to increase the percent dissociation? 

 

Could you please explain youranswer in more detail!

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.
