WebArrhenius defines acids and bases by the dissociation products that are formed when the acid or base is added to water, while Bronsted and Lowry define acids and bases by the reactions that occur when both are added together. WebIn this process, ammonia is the Lewis base and BH 3 is the Lewis acid. Generally, the Lewis definition of acids and bases is the most useful because it is the most inclusive of the three definitions. For example, the Brnsted-Lowry definition of an acid includes HF but not BH 3, which doesn't lose a proton when attached by the lone pairs on a ...
