Proposta de método padrão para determinação de ácido fosfórico

Abstract

Analytical Chemistry aims to develop equipment and methods that increasingly facilitate plus chemical analysis processes, with the analytical frequency being of utmost importance. importance for this. In this area, the term "standard method" refers to a systematic and standardized procedure for carrying out a chemical analysis. That method is carefully developed and validated to ensure reliable results and accurate in determining the amount or concentration of a substance specific in a sample. Examples of standard methods may include techniques such as titration, chromatography, spectroscopy, among others. These methods are essential for obtaining reliable data in chemical analysis, whether for quality control, research scientific or other analytical applications. The method follows a specific set of steps, reagents and conditions experimental, ensuring consistency and reproducibility in results. Still, substances do not always have this method, therefore, this work aims to achieve the objective of proposing a standard method for the determination of acid phosphoric acid, to this end, neutralization titrations and potentiometric measurement to verify compliance within the standards expected analytics
