Lab Report

Analysis of the Phosphate in Cola Jay Acker Matt Craig Michael Harrison Rachel Sherman Chemistry101 Laboratory Instructor: Barbara Lewis November 14, 2011 Our signatures allude that this document represents my own work. Excluding shared data, the information, thoughts and ideas are my own, except as indicated in the references. Introduction: Our research group was transferred to a study weed company. The goal of this science lab was to analyze as many another(prenominal) an(prenominal) of the rivals colas as possible. We are investigation the orthophosphate content in different rivals cola to figure the. To do this we first had to reign out how the spectrophotometer 20 works. therefore utilize them to analyze the channel surrounded by the show of the different colas and the wavelength of light absorbed. one time that is through with(p) we will be able to tell how frequently phosphate niggardliness is in each rivals cola.

Allowing us to give out our results to our cola company Results: turn 1: affinity mingled with % transmittance and wavelength in quaternarysome solutions embark 2: blood betwixt Absorbance and Wavelength for four solutions finger 3: race amid % transmittance and constriction of KMnO4 at 530nm mannikin 4: Relationship amid absorbance and tightfistedness in KMnO4 at 530nm check 5: Relationship in the midst of Percent Transmittance and Wavelength in K2HPO4 0 Figure 6: Relationship betwixt Absorbance and Wavelength in K2HPO4 Figure 7: Relationship between % T and Wavelength on 0.0002M K2HPO4 Figure 8: Relationship between % T and tightfistedness in dilute Solution of K2HPO4 Figure 9: Relationship between Absorbance and stringency in diluted Solution of K2HPO4 Figure 10: Relationship between Absorbance and absorption of K2HPO4 in Cola Products computer science of the concentration of phosphate in cola sample using data from figure 10 niggardliness vs. Absorbance of .001 M Potassium Permanganate apparent motion line equation: y=5635.1+2.0125...If you want to get a full essay, order it on our website: Orderessay
