![]() You can plot the graphs using Excel as demonstrated in the introductory video from this Module or in the link below and add them to the Word file for submission: Make sure to include a title, your name, section number, and ALL the calculations involved with the assignment. The calibration plots must have the correct title of the graph, X and Y-labeling, linear equation, R-square value and slope displayed to earn full points. In this section, you will need to submit a typed Word document answering all of the post lab summary questions provided in in the lab manual ( There are five questions, skip Question 6 in, each question is worth 4 points, total 20 points) and use the absorbance and concentration data below to create two calibration plots, one from serial dilution and the other from parallel dilution ( 10 points each). To assist you with understanding serial dilutions, click on the link below for a YouTube video: Prepare five different concentrations (total volume can range from 5-50 mL) using parallel and serial dilutions.Ģ. Describe how to use the UV-Vis spectrometer. Depending on the molar absorptivity value of each dye, the concentrations you use may vary, you can use any concentration within the range of 0.01 M to 0.1 M. You can assume the stock concentration of the dye is to be 0.1 M. Here is some specific information you need to include for this pre-lab assignment:ġ. You will need to show how to perform parallel and serial dilution calculations. ![]()
