Course Description

In this lecture, students will learn chemical analysis methods to measure the electrical and electrochemical character of the system, both in classical and instrumental analysis. Classical analysis—titrimetry—is carried out by measuring the solution’s pH, emf, or conductivity during titration to determine the equivalence point. Students are expected to be able to compare with titrimetric analysis using color indicators. Instrumental analysis with an electrochemical approach leads students to analyze metal ion species, their contents and retrieve these metals from solution, analyze metal ions in solution at a trace level with a more environmentally friendly method (clean technology). Students can recognize the approach electricity and electrochemistry and compare it with other techniques to solve the chemical analysis of ions at low concentrations, applying these methods to the recovery process metals from solution
