Resumen de Troubleshooting 101: An Instrumental Analysis Experiment.
An experiment is described where students troubleshoot a published procedure for the analysis of ethanol. UV�vis spectroscopy is used to measure the change in absorbance upon reaction of dichromate with ethanol. The experiment requires the students to critically evaluate their experimental results to correct a fundamental flaw in the original written procedure. Students can use the results and the corrected procedure to understand the limits of sensitivity of the instrumentation used for the absorbance measurements.
