Objective

To determine the concentration of Au+3 left unreacted in solution in the fiber solutions using electrochemistry.

Description

  1. Make the following dilutions of chloroauric acid to create a calibration curve:
    • 5.00 mM
    • 1.00 mM
    • 500 μM
    • 100 μM
    • 50.0 μM
    • 10.0 μM
    • 5.00 μM
    • 1.00 μM
    • 500 nM
    • 100 nM
  2. Add 0.1 mL of 0.5 mM aqueous KNO3 to each solution.
  3. Use cyclic voltammetry with two glassy carbon electrodes (0.35 cm2), scanning from -0.5 V to 1.7 V and returning to -0.8 V for each solution.

Notes

This area is for any observations or conclusions that you would like to note.


Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized.
