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)
the dissociation constant for hydrochloric acid is greater than the dissociation constant for acetic acid.
the ph of a solution of hydrochloric acid must be less than the ph of a solution of acetic acid.
if the initial concentration of each acid is the same, then acetic acid will produce more h₃o⁺ ions than hydrochloric acid.
a solution of hydrochloric acid at equilibrium will have a greater concentration of solute than a solution of acetic acid at equilibrium.

Explanation:

A strong acid like hydrochloric acid dissociates completely in solution, having a large dissociation constant. A weak acid like acetic acid only partially dissociates, with a small dissociation constant. The pH depends on concentration, so we can't say the pH of HCl is always lower than acetic - acid's without concentration info. If concentrations are the same, HCl will produce more H₃O⁺ ions as it fully dissociates. At equilibrium, acetic - acid solution has more undissociated solute as it is a weak acid.

Answer:

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