G. C. 1 - 6: LABORATORY REPORT Name: Griffen Bono Z Number: Z23558213 Lab TA’s Name and Section Number: Timothy Foo – Section 023 A statement Accountability: “I certify that this is my own work, and I understand that if I am found to be in violation of the honor code, I will be subject to the highest penalty.” SUMMARY OF THE VIDEO This video explains Beer’s Law, and leads us through a lab to show the students how it works, as well as how to construct a calibration curve using lab quest 2. He has 6 vials, starting on the left and going to the right, .4 molar nickel sulphate solution, .32 molar, .24 molar, .16 molar, .08 molar, and distilled water. Those solutions were then placed into cuvettes respective to their molar value. Each cuvette is then placed into a spectrometer, which shines a light through the solution. This method tells you how much light is being absorbed and how much is being transmitted by using a detector on the other side that quantifies the light. The distilled water is placed in the device first as a control to let the machine figure out how much light is being absorbed by the cuvette itself, and to calibrate the light in general. We then start with the most concentrated solution. The device displays a graph that shows the user what wavelength of light is being absorbed and what is being transmitted. In this case, the green is being transmitted while the purple and red colors are being absorbed. The device mode is then changed
