This lab was not actually done in person, so I did not have the proper references in terms of the instruments for this lab assignment. I am just trying to gain a better understanding of these questions despite not actually seeing it in the lab! I included all of the charts and diagrams that were included in the lab document. Thank you!

Post lab questions 1) What is the difference between filter colorimeter and spectrophotometer? 2) What is the purpose of aligning the detector and how would that affect absorbance measurement? 3) How would you classify this spectrophotometer? Is it a single beam or a double beam spectrometer and why? 4) Looking at the chart you have in the first page of this lab, what color is absorbed by yellow solution? 5) What is complementary color?
