Extracts from this document...

Introduction

The use of different leaves' effects on the chromatography I. Introduction Research Question How does the use of different colored leaves affect the amount of colour traveled within paper chromatography? Hypothesis A leave with the highest concentration of pigments present will have the greatest amount of pigments traveled within paper chromatography. Null Hypothesis There is no significant different in the amount of chlorophyll traveled in paper chromatography within the use of different plant leaves. Variables Independent Variable The use of different colored plant leaves for amount of chlorophyll traveled within paper chromatography. Dependent Variable The measure of the amount of chlorophyll traveled with the paper chromatograph (cm). Controlled Variables Volume of solution The volume of each sample throughout the experiment is 20 cm � 0.05 cm. The volume of each solution should be the same to get more accurate results on the amount of chlorophyll that travels throughout the paper chromatograph. ...read more.

Test tube 1 showed no color within the paper chromatograph. However, after the first 30 minutes, a slight break within the chromatograph of Test tube 2 is present. After 1.0, Sample 1 has shown a slightly darker shade of yellow than recorded previously. For sample 2, there is an increase in the shade of green within the breaking point on the chromatograph. For sample 3, there is no significant change; however, there is a slight change in the colour of the paper chromatograph. For sample 4, a light shade of pink is present at the top of the paper chromatograph. After 1.5 hours. Yellow leaves show a greater range of yellow shade within the chromatograph, there is no change in the amount traveled. For sample 2, there are 4 shades of green and 2 shades of yellow within the chromatograph. There is no increase in the amount traveled within the chromatograph. For sample 3, there is no change in the number of shades within the chromatograph and the amount traveled. ...read more.

Conclusion

For sample 2, there are 4 shades of green and 2 shades of yellow within the chromatograph. There is no increase in the amount traveled within the chromatograph. For sample 3, there is no change in the number of shades within the chromatograph and the amount traveled. For sample 4, there are 2 shades of green, one of the shades has darkened within the chromatograph, and there is a darker shade of pink colour present throughout the chromatograph. The experiment can be repeated twice, so the data table will represent results for both trials and the average. The data tables include the colored leaves for each sample for the experiment the colour within the chromatograph and the amount traveled within the chromatograph (cm) with an uncertainty of � 0.05 cm. Thus, the experiment has been carried on for three times to achieve more accurate results and to represent a clearer bar graph and pie graph for the analysis throughout the analysis and the t-tests demonstrated further on in this paper. ...read more.
