Question

Hydrochloric acid is a strong acid. Acetic acid is a weak acid. Which statement about hydrochloric acid and acetic acid is correct? (1 point)

A. A solution of hydrochloric acid at equilibrium will have a greater concentration of solute than a solution of acetic acid at equilibrium.

B. If the initial concentration of each acid is the same, then acetic acid will produce more H30 ions than hydrochloric acid

C. The pH of a solution of hydrochloric acid must be less than the pH of a solution of acetic acid

D. The dissociation constant for hydrochloric acid is greater than the dissociation constant for acetic acid.

Answer 1

a solution of acetic acid and sodium acetate

Step-by-step explanation:

A buffer solution is defined as a solution which resist a change in pH when small quantity of a strong acid or a strong base are added. A buffer solution is made up of mixture of a weak acid and its conjugate base or a mixture of a weak base and its conjugate acid.

Acetic acid is the only option because it is a weak acid with a corresponding conjugate base, acetate. Unlike a solution of sulfuric acid and sodium sulfate in which the sulfuric acid is a strong acid which doesn’t qualify it to be a buffer solution. The remaining options have different acid compounds paired together which makes them invalid too.
