Introduction:
Our research group was transferred to a major weed company. The goal of this laboratory was to analyze as many an(prenominal) of the rivals colas as possible. We are investigating the orthophosphate content in different rivals cola to determine the. To do this we first had to decree out how the spectrophotometer 20 works. Then using 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 to tell how much phosphate constriction is in each rivals cola.



Allowing us to give our results to our cola company
Results:
turn 1: affinity mingled with % transmittance and wavelength in foursome solutions


Figure 2: Relationship betwixt Absorbance and Wavelength for four solutions


Figure 3: 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 tightfistedness in dilute Solution of K2HPO4


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 sample using data from figure 10
Concentration vs. Absorbance of .001 M Potassium Permanganate trend line equation: y=5635.1+2.0125...If you want to get a full essay, order it on our website: Orderessay
