Web30 jul. 2024 · Acids are substances that provide hydrogen ions (H +) and lower pH, whereas bases provide hydroxide ions (OH –) and raise pH. The stronger the acid, the more readily it donates H +. For example, hydrochloric acid and lemon juice are very acidic and readily give up H + when added to water. WebArrhenius 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 − ).
