Cálculo de pH de disoluciones tampón polipróticos | Química Analítica I

TitGer – an electronic worksheet for simulating the titration of a mixture of polyprotic species. The aim of this paper is to present a simple way of treating the general equation for acid-base titrations based on the concept of degree of dissociation, and to propose a new spreadsheet approach for poliprtoicos the titration of mixtures of polyprotic compounds.

The general expression, without any approximation, is calculated a simple iteration method, making number manipulation easy and painless.

Several graphs are drawn for helping visualizing the titration behavior. A Monte Carlo function for error simulation was also implemented.

Two examples for titration of alkalinity and McIlvaine buffer are presented. Este trabalho tem dois objetivos: No caso do TitGer 1.

A planilha TitGer 1. Seu algoritmo simples pode ser acompanhado por qualquer leitor interessado no assunto. Na Figura 2o valor do incremento foi 0,25 mL.

A Figura 5 foi gerada automaticamente no TitGer na pasta ‘Distr. Nova11 Acta, poliprogicos Rio de Janeiro, Nova149. New York New York,p. Fort Worth,p. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License.
