Question 1

Which of the acids (HX, HY, or HZ) shown in the diagrams above has the lowest percent dissociation in water? Assume each box contains the same total number of acid molecules initially.

Accepted Answer

HX

Question 2

Given the diagrams above, which acid is the strongest based on the number of $$\mathrm{H_3O^+}$$ and $$\mathrm{A^-}$$ ions present?

Accepted Answer

HY

Question 3

If each box in the diagram represents 0.10 M solutions, which acid would have the highest pH?

Accepted Answer

HX

Question 4

Based on the diagrams, which acid would be most suitable for preparing a buffer with its conjugate base?

Accepted Answer

HZ

Question 5

If you were to add a small amount of strong base to each solution, which acid solution would resist a pH change the most?

Accepted Answer
