Question

acid base solutions quick check
hydrochloric acid is a strong acid. acetic acid is a weak acid. which statement about hydrochloric acid and acetic acid is correct? (1 point)
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.
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.

Explanation:

Strong acids like hydrochloric acid completely dissociate in solution, having a large dissociation constant. Weak acids like acetic acid only partially dissociate, resulting in a smaller dissociation constant. If initial concentrations are equal, strong acids produce more $H_3O^+$ ions. Also, pH depends on concentration, not just acid - strength. And at equilibrium, a strong - acid solution has less undissociated solute.

Answer:

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