Ramen Spectroscopy

Experiment 8 : Ramen spectrographic analysis Objective: To utilize Raman Spectroscopy as an analytic chemistry tool to determine (i) the writing of an uncharted put out/ benzol mixture (ii) the amount of ethyl alcohol in vodka. Pre-lab questions: 1) What is a calibration curve and how would you go close to constructing iodin? A calibration curve shows the response of an analytical system to known quantities of an analyte. To construct a calibration curve, we beginning grind away known samples of the analyte covering a stray of densitys expected for the unknowns and time the response of the analytical procedures of these standards to generate direct data. After the measurement is done, a linear graph of the signal data against analyte concentration is plotted. The concentration of the unknown sample is then(prenominal) determined exploitation the equation of the calibration curve. Data assembling: (i) immersion of benzene (% volume) 5 10 20 30 40 60 70 80 Benzene /chloroform mixture rule book of benzene added 0.5 mL 1 mL 2 mL 3 mL 4 mL 6 mL 7 mL 8 mL Wave number(cm1) 1586.712262 1586.712262 1586.712262 1586.712262 1586.712262 1586.712262 1586.712262 1586.712262 summit counts 62.9508 48.53701 107.7373 137.6723 183.4448 279.8358 360.6083 392.8723 Concentration Volume of of centiliter (% chloroform volume) added 95 90 80 70 60 40 30 20 9.
