Answer:
increases the H + ion concentration in aqueous solution
Step-by-step explanation:
An Arrhenius base is a compound that increases the OH − ion concentration in aqueous solution. Arrhenius theory, theory, introduced in 1887 by the Swedish scientist Svante Arrhenius, that acids are substances that dissociate in water to yield electrically charged atoms or molecules, called ions, one of which is a hydrogen ion (H+), and that bases ionize in water to yield hydroxide ions (OH−). Arrhenius Definition of acids. An acid is a substance that dissociates in water to produce H+ (hydrogen ions) Arrhenius Definition of strong acids. A strong acid is a substance that fully dissociates in water to give hydrogen ions. Arrhenius Definition of weak acids.
