Consider the following statement:
'Acids are substances that dissociate in water to give hydrogen ions $\text{H}^+$ (aq), and bases are substances that produce hydroxyl ions $\text{OH}^-$ (aq).'
The above statement is based on which one of the following concepts?

According to the Arrhenius concept, an acid is a substance that dissociates in water to give hydrogen ions $\text{H}^+$ (aq), and a base is a substance that dissociates in water to yield hydroxyl ions $\text{OH}^-$ (aq).

The Bronsted-Lowry concept defines an acid as a proton donor and a base as a proton acceptor.

The Lewis concept defines an acid as an electron pair acceptor and a base as an electron pair donor.

Thus, the given statement is based on the Arrhenius concept.

Answer: Arrhenius concept
