Oxidation of Alcohol Experiment 17 10/14/07 Heather Wilson Lab Partner: Caitlin de Blanc TA: Ted Matson Introduction In this experiment, the rate of oxidation of ethanol to produce ethanal using the oxidizing agent potassium dichromate was determined, using the procedure outlined by van Koppen (van Koppen, P. A. M. General Chemistry Laboratory Manual (UCSB). Copyright © 2007 Hayden- McNeil, Plymouth, MI. pp. xxx-xxx.). Data The absorbance of the oxidizing sample of ethanol was recorded over time onto a computer by a computer-integrated spectrophotometer. Absorbance of Light in 330 to 440 nm range Time (sec) Absorbance 10.635 0.125 31.114 0.111 51.754 0.099 72.271 0.087 92.82 0.077 113.348 0.067 133.877 0.061 154.415 0.055 174.903 0.049 195.512 0.047 216.133 0.039 236.631 0.037 257.149 0.034 277.727 0.034 298.247 0.032 318.877 0.027 339.529 0.026 360.078 0.026 380.636 0.025 401.159 0.023 421.673 0.023 442.293 0.023 462.861 0.022 483.513 0.022 504.082 0.022
