Through this experiment, I learned about chromatography which is a versatile technique for determining the chemical composition of a wide variety of materials and only requires small amounts of samples for analysis. We did paper chromatography in this experiment which is a separation technique that uses a liquid mobile phase and a paper stationary phase. The purpose of this experiment is to use paper chromatography to separate the color components contained in different flavors of Kool-Aid drink mix and compare the color components to samples of Fd&C dyes. After performing the experiment, we had to measure the distance the dyes traveled and

For example, it was very important to cover the beaker when developing the chromatography paper but I didn’t immediately cover the beaker with foil but rather covered it with my hands then I moved it around which was a mistake because it was crucial that we kept the beakers stable or else the direction of the dyes would’ve moved. I identified that my watermelon and cherry Kool-Aid had a closer Rf to the red dye that I had. Then my blueberry Kool-Aid was closer to the R40 pigment and the grape was closer to the green dye....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
