In Section 6.2d, we saw that the pK, of an acid is
equal to the pH of the solution at which half the acid
has dissociated into its conjugate base. UV-vis
spectroscopy can be used to measure the relative
concentrations involved if the acid or conjugate base
absorbs UV-vis light. With this in mind, suppose that
a particular acid has a Amax of 312 nm. The figure
here shows the absorbance at that wavelength as
a function of pH. What is the pk, of the acid?

Absorbance at 312 nm
Explain why this is the correct spectra for these molecules. Identify a specific absorption band which identifies each characteristic functional group of the chosen molecule.
Explain why or why not the fingerprint region of the IR spectrum cannot be predicted. Use the basis for IR absorption in
your argument.
