The concepts of acids and bases are of great interest in chemistry, however, the approach to this topic is being seen in a distorted way without considering the context of its development, which ends up causing generalizations in its understanding, which causes a misunderstanding of these concepts. by the students. One of the main generalizations is the approach found in textbooks, which do not take into account the historical context in which these concepts were inserted, thus, the importance of evaluating the history of science in Chemistry textbooks is worth considering as a way of aiding teaching. of these concepts. Acids and bases have been known since antiquity and, over time, scholars tried to define them, a consequence of which were the great scientific contributions to the sciences, such as those of Boyle, Joseph Black, Lavoisier, and many other names, until reaching the most current definitions for acids and bases. Therefore, the objective of this work is to evaluate the inclusion of the history of Science in the content of acids and bases in the PNLD 2018 Chemistry textbooks. The methodology for evaluating the works consisted of three categories: Quantity of historical content, approach and quality of historical information. In addition to analyzing four criteria: anecdotal stories; linearity, absence of the broader historical context and consensuality. Among the books evaluated, some do not present historical content, and those that do, for the most part, are presented in a minimal and unsatisfactory way. In only one of the works does the historical content satisfy, in relation to the inclusion of the history of chemistry in the teaching of acid/base concepts, in addition to the distorted views on science appearing frequently in the LDQ of the PNLD 2018. The PNLD points to the history of Science as a fundamental characteristic that must be included in textbooks, however, this does not occur satisfactorily and, despite there being broader definitions regarding the topic, Arrhenius' definitions are the most used or the only one covered in PNLD chemistry textbooks. 2018.
