Arrhenius acids

Arrhenius acids are substances that increase the concentration of hydrogen ions (H⁺) when dissolved in water. This release of H⁺ ions makes the solution acidic, giving it properties like a sour taste and the ability to react with certain compounds. For example, hydrochloric acid (HCl) dissociates in water to produce H⁺ and chloride ions. This definition helps us understand acids at a molecular level, focusing on their behavior in aqueous solutions and their role in producing acidity through the release of hydrogen ions.
