Abstract Brønsted acid-base theory is one of the most important modular in general chemistry, which usually begins from aqueous solution of weak acids. This theory will be endowed with expanded application if all proton compounds are considered. If so, the Ka value will expand more than 100 orders of magnitude. The evaluation of the “strongest” acid or base is a common topic among students, which provides a nice chance to introduce the concepts of superacid and superbase for students. These concepts will expand the knowledge horizon of students, meanwhile deepen the understanding of Brønsted acid-base theory, which helps the study of analysis chemistry, inorganic and organic chemistry in the future.
