Consider the following statement: 'Acids are substances that dissociate in water to give hydrogen ions H ^+ (aq), and bases are substances that produce hydroxyl ions OH ^- (aq).' The above statement is based on which one of the following concepts?
C. Arrhenius concept
According to the Arrhenius concept, an acid is a substance that dissociates in water to give hydrogen ions H ^+ (aq), and a base is a substance that dissociates in water to yield hydroxyl ions 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
