Using data from Table 1 plot a graph similar to Figure 4 in the manual that you will label as “Figure A - Bromophenol Blue Stock Solution Absorbance Spectrum”. Remember all graphs need x-y-axis labels and titles. Plot the graph of order 2 polynomial as the best fit curve. The best-fit curve should show the equation of the line, it does not need to pass through the origin (0,0).
