Sam Eichenblatt A2 Discussion lab 8 The experiment that was preformed involved calculating the concentration of a solution using the absorbance of light. First the solutions were made with different levels of Fe3+ and SCN- then each solution was made and placed in a machine that tested the absorbance of the solution. Then using absorbance= constant*concentration we were able to find the concentration of all elements in the solution and the constant of the solution. The graph of absorbance vs concentration shows the relationship is linear

Unformatted text preview: and that beer’s law holds true. The second experiment calculated the Keq using the same method as the first part. The absorbance was calculated and concentration of all parts of the solution from that. From here the Keq can be calculated by multiplying the concentration of the products and dividing them by the product of the concentration of the reactants. The Keq is large which means that there are more products than there are reactants and that the equilbriam happens when there are more products than reactants....

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
