L. Wayman & G. C. Weatherly Bulletin : Inst. There are several ways to define acids and bases, but pH specifically only refers to hydrogen ion concentration and is applied to aqueous (water-based) solutions. When water dissociates, it yields a hydrogen ion and a hydroxide. See this chemical equation below. H 2 O H + + OH -.
