How can you tell? 3) Which compound is more strongly adsorbed on silica, ortho- or para- nitroaniline? Correlate the R, values with the structures.

zero absorbance or 100 %T. If not, adjust the spectrophotometer accordingly. (2) Set the wavelength of the spectrophotometer to 400 nm. . Place the stock solution (Solution 5) in a cuvet following the "blank solution procedure" as above. Measure and record the wavelength and absorbance. Scan the wavelength range of the spectrophotometer while recording absorbance values. You will need to scan manually, setting the absorbance at zero (100% T) with the blank solution (0.1 M HNO3) at EACH chosen wavelength before recording the absorbance of the stock solution. Plot the data, absorbance, A (y-axis) versus the wavelength, λ (x-axis), to determine the λmax, the wavelength where maximum absorbance occurs for the cobalt ion.
