We work to identify liquids that would meet all these different pH values. Arrhenius acids are compounds that release hydrogen ions (H +), while Arrhenius bases are those that release hydroxyl ions (OH -). Many acids are very helpful to use in everyday life.
We use a pH scale to classify substance that ranges from 0 to 14, with 7 being neutral (meaning neither an acid nor a base. Course Hero member to access this document.
