Resumo: Buffering systems are widely used in all areas of science that involve the use of aqueous solutions, such as pharmaceutical, environmental and analytical chemistry. However, there are several approaches and parameters that can be employed to try to explain buffering behavior, such as the Van Slyke buffer value, Kolthoff’s buffer capacity, acidity, alkalinity, and others, although they are unable to provide a global explanation of it. In this paper, we propose the Buffering Function, which is a fundamental equation that enables explanation of all types of buffering behavior and existing parameters, without use of the Henderson-Hasselbalch approach

Entretanto, há várias propostas e parâmetros que tentam explicar o comportamento tampão, tais como poder tamponante de Van Slyke, capacidade tamponante de Kolthoff, acidez, alcalinidade and outros, mas todos são incapazes de apresentar uma explicação global para esse comportamento. Neste artigo, propomos a Função Tamponante, que é uma equação fundamental que permite explicar todos os tipos comportamento tampão e os parâmetros já proposto, sem usar a Equação de Henderson-Hasselbach.Universidade Federal de Viçosa - UFV2020-09-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1011010.18540/jcecvl6iss3pp0387-0396The Journal of Engineering and Exact Sciences; Vol. 6 No. 3 (2020); 0387-0396The Journal of Engineering and Exact Sciences; Vol. 6 Núm. 3 (2020); 0387-0396The Journal of Engineering and Exact Sciences; v. 6 n. 3 (2020); 0387-03962527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/10110/5921Copyright (c) 2020 The Journal of Engineering and Exact Sciencesinfo:eu-repo/semantics/openAccessde Oliveira, André Fernando2021-02-23T20:12:27Zoai:ojs.periodicos.ufv.br:article/10110Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2021-02-23T20:12:27The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
