An
Arrhenius base is a substance that dissociates in water to form hydroxide
ions (OH⁻).
In this example lithium hydroxide is an Arrhenius base:
LiOH(aq) → Li⁺(aq)
+ OH⁻(aq).
An Arrhenius acid is
a substance that dissociates in water to form hydrogen ions or protons (H⁺).
For example hydrochloric
acid: HCl(aq) → H⁺(aq)
+ Cl⁻(aq).
