Acids and Bases
An acid (often represented by the generic formula HA [H+A−]) is traditionally considered any chemical compound that, when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than 7.0.
A base is most commonly thought of as an aqueous substance that can accept protons. A base is also often referred to as an alkali (only if OH− ions are involved).
