Hydrochloric acid is a strong acid. Acetic acid is a weak acid. Which statement about hydrochloric acid and acetic acid is correct?(1 point) Responses A solution of hydrochloric acid at equilibrium will have a greater concentration of solute than a solution of acetic acid at equilibrium. 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 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. 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.
The statement that is correct is: The dissociation constant for hydrochloric acid is greater than the dissociation constant for acetic acid.
The correct statement about hydrochloric acid and acetic acid is: The dissociation constant for hydrochloric acid is greater than the dissociation constant for acetic acid.
To determine which statement about hydrochloric acid (HCl) and acetic acid (CH3COOH) is correct, we need to consider their strength as acids and the dissociation constants.
1. Strong acid vs. weak acid: Hydrochloric acid is a strong acid, meaning it completely dissociates into ions when dissolved in water. Acetic acid is a weak acid, which means it only partially dissociates into ions.
2. Concentration of solute: Since hydrochloric acid is a strong acid, it completely dissociates, resulting in a greater concentration of solute (H+ ions) in the solution than acetic acid, which only partially dissociates.
3. Dissociation constant: The dissociation constant (Ka or acid ionization constant) measures the extent of acid dissociation in water. A higher dissociation constant indicates a stronger acid. In this case, hydrochloric acid has a larger dissociation constant than acetic acid, making it a stronger acid.
4. pH: The pH of a solution is a measure of its acidity. Since hydrochloric acid is a stronger acid, it produces more H+ ions when dissociated, resulting in a lower pH compared to acetic acid.
5. H3O+ ion production: If the initial concentration of each acid is the same, it means we have the same moles of acid in solution. Since hydrochloric acid is a stronger acid, it will dissociate more fully, producing more H3O+ ions than acetic acid.
Therefore, the correct statement in this case is: "If the initial concentration of each acid is the same, then acetic acid will produce more H3O+ ions than hydrochloric acid."
