2. Plot the following data as absorbance vs concentration of X in excel. Absorbance, A Molar Concentrationof X. 0.045 3.0x 10-4 mol/L. 0.097 6.2x 10-4mol/L. 0.14 9.0 x 10-4 mol/L. 0.35 2.2x 10-3mol/L. 0.51 3.2x 10-3mol/L. When plotting in excel make sure that ( in EXCEL, not hand written ) you label each axis and place a title that includes.
Trial 1: 25 ml crystal violet, 150 ml room temp distilled water, 25 ml sodium hydroxide (a 1:8 dilution of stock reactants) Trial 2: 25 ml crystal violet, 150 ml hot distilled water, 25 ml sodium hydroxide ...The order of the reaction is first in NaOH and first in CV, but even if I'm wrong about that and it's one or the other, the most.

The peaks, which are also called absorbance bands, correspond with the various vibrations of the sample's atoms when it's exposed to the infrared region of the electromagnetic spectrum. For mid-range IR, the wave number on the infrared spectrum is plotted between 4,000 to 400 cm-1. The Y-Axis: Absorbance or Frequency.
in Excel.) Then, construct a scatter plot (with lines connecting the data points this time!) of absorbance (y-axis) vs. wavelength (x-axis). Overlay the results for both colored solutions on the same graph. This type of plot is called an absorption spectrum. Since absorption is based on a ratio of intensities, it is a unit-less value. 7..
After making an adjustment to the spectral scans of AR and TZ from Part I, sum the respective absorbance values at each particular wavelength to create a new graph. The graph is a plot of absorbance (sum of AR and TZ) vs. wavelength. Plot this graph together with the graph created in Part II. Discuss any questions about these graphs with your.
