Analysis of the Phosphate in dope Jay Acker Matt Craig Michael Harrison Rachel Sherman Chemistry101 research laboratory Instructor: Barbara Lewis November 14, 2011 Our signatures insinuate that this document represents my own work. Excluding sh ard data, the information, thoughts and ideas are my own, except as indicated in the references. Introduction: Our research group was transferred to a major weed company. The goal of this laboratory was to see as many an(prenominal) of the rivals colas as possible. We are investigating the inorganic phosphate content in contrastive rivals cola to determine the. To do this we first had to decree out how the spectrophotometer 20 works. Then utilise them to analyze the descent surrounded by the color of the different colas and the wavelength of light absorbed. Once that is through with(p) we will be capable to tell how much phosphate constriction is in individually rivals cola.

Allowing us to give our results to our cola company Results: turn 1: affinity mingled with % transmittance and wavelength in foursome solutions go out 2: blood betwixt Absorbance and Wavelength for four solutions rule 3: kind between % transmittance and constriction of KMnO4 at 530nm Figure 4: Relationship between absorbance and concentration in KMnO4 at 530nm Figure 5: Relationship between Percent Transmittance and Wavelength in K2HPO4 0 Figure 6: Relationship between Absorbance and Wavelength in K2HPO4 Figure 7: Relationship between % T and Wavelength on 0.0002M K2HPO4 Figure 8: Relationship between % T and tightness in dilute Solution of K2HPO4 Figure 9: Rela tionship between Absorbance and stringency ! in Diluted Solution of K2HPO4 Figure 10: Relationship between Absorbance and Concentration of K2HPO4 in Cola Products Calculation of the concentration of phosphate in cola savour using data from figure 10 Concentration vs. Absorbance of .001 M Potassium Permanganate trend line equation: y=5635.1+2.0125...If you take to get a full essay, order it on our website: OrderEssay.net
