Based on standard acid-base chemistry principles, let's evaluate each statement.
-
The HA is the acid and the H3O+ is its conjugate base.
- False: HA is the acid, and its conjugate base would be A-. H3O+ is actually the conjugate acid of water (H2O).
-
The H2O is acting as a base and the H3O is its conjugate acid.
- True: In acid-base reactions, H2O can act as a base when it accepts a proton (H+) to become H3O+ (the conjugate acid of water).
-
The solution shows an acid that completely dissociated into its ions.
- This statement cannot be accurately judged without additional information about the acid in question. If it’s a strong acid, it would fully dissociate; if it’s a weak acid, it would not.
-
The solution contains a strong acid.
- This statement also cannot be confirmed without additional information about the specific acid. It depends on the nature of HA.
In summary, based on typical scenarios in acid-base chemistry, the only outright true statement (assuming common understanding and no additional context) would be the second one regarding H2O as a base. The first statement is false, while the last two depend on additional context regarding the acid in question.
