Acids and bases can be described using the Arrhenius model: acids produce H+ ions in aqueous solutions, while bases produce OH- ions. We can identify acidic and basic solutions using their distinct and often contrasting properties, some of which you are likely familiar with! The strength of an acid or base can also vary and depends on how much it dissociates in solution.
