• Resumen

  • Fully functional and inexpensive electrodes assembled by students have previously been described for use in potentiometric titrations. A detailed analysis of graphs generated from titration data obtained with such electrodes can offer students greater insight into the nature of solubility and practical use of the Nernst equation. These titration data can also be used by students to calculate the solubility product of the precipitant formed by the chemical reaction between the analyte and titrant.
