Analysis of the Phosphate in sess Jay Acker Matt Craig Michael Harrison Rachel Sherman Chemistry101 research lab Instructor: Barbara Lewis November 14, 2011 Our signatures insinuate that this document represents my own work. Excluding sh ared data, the information, thoughts and ideas are my own, except as indicated in the references. Introduction: Our research conclave was transferred to a major weed company. The goal of this laboratory was to try out as many an(prenominal) of the rivals colas as possible. We are investigating the orthophosphate content in antithetic rivals cola to determine the. To do this we first had to decree out how the spectrophotometer 20 works. Then exploitation 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 able-bodied to tell how much phosphate constriction is in severally rivals cola.

Allowing us to give our results to our cola company Results: turn 1: affinity mingled with % transmittance and wavelength in foursome solutions control 2: kind betwixt Absorbance and Wavelength for four solutions encipher 3: human relationship 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 minginess in dilute Solution of K2HPO4 Figure 9: Relationship between Absorb! ance 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 adjudicate using data from figure 10 Concentration vs. Absorbance of .001 M Potassium Permanganate trend line equation: y=5635.1+2.0125...If you indirect request to get a full essay, order it on our website: OrderEssay.net
