Lab Report

Analysis of the Phosphate in low-down 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 bed data, the information, thoughts and ideas are my own, except as indicated in the references. Introduction: Our research assembly was transferred to a major weed company. The goal of this laboratory was to psychoanalyze as many an(prenominal) of the rivals colas as possible. We are investigating the orthophosphate content in assorted rivals cola to determine the. To do this we first had to decree out how the spectrophotometer 20 works. Then use 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 sufficient to tell how much phosphate constriction is in from each one rivals cola.

Allowing us to give our results to our cola company Results: turn 1: affinity mingled with % transmittance and wavelength in foursome solutions dactyl 2: kinship betwixt Absorbance and Wavelength for four solutions propose 3: kin 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 a nd constriction in dilute Solution of K2HP! O4 Figure 9: Relationship 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 warning using data from figure 10 Concentration vs. Absorbance of .001 M Potassium Permanganate trend line equation: y=5635.1+2.0125...If you requisite to get a full essay, order it on our website: BestEssayCheap.com
