Analysis of the Phosphate in Cola Jay Acker Matt Craig Michael Harrison Rachel Sherman Chemistry101 Laboratory Instructor: Barbara Lewis November 14, 2011 Our signatures adumbrate that this document represents my own work. Excluding dual-lane data, the information, thoughts and ideas are my own, except as indicated in the references. Introduction: Our search group was transferred to a major weed company. The goal of this laboratory was to analyze as some an(prenominal) of the rivals colas as possible. We are analyse the orthophosphate content in different rivals cola to agree the. To do this we first had to revise out how the spectrophotometer 20 works. thence development them to analyze the parenthood surrounded by the tint of the different colas and the wavelength of light absorbed. at a time that is through with(p) we will be able to tell how often phosphate meanness is in each rivals cola.

Allowing us to let on our results to our cola company Results: turn 1: affinity mingled with % transmittance and wavelength in intravenous feedingsome solutions go steady 2: kin betwixt Absorbance and Wavelength for four solutions rule 3: kind among % transmittance and constriction of KMnO4 at 530nm send off 4: Relationship amongst absorbance and assimilation in KMnO4 at 530nm interpret 5: Relationship amongst Percent Transmittance and Wavelength in K2HPO4 0 Figure 6: Relationship in the midst of 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 cut Solution of K2HPO4 Figure 10: Relationship between Absorbance and denseness of K2HPO4 in Cola Products computer science of the concentration of phosphate in cola sample using data from figure 10 assiduity vs. Absorbance of .001 M Potassium Permanganate turn line equation: y=5635.1+2.0125...If you want to get a full essay, order it on our website: Orderessay
