Spectrophotometric Determination of the Dissociation Constant of an Acid-Base Indicator Using a Mathematical Deconvolution Technique
Alter, Krystyn P.; Molloy, John L.; Niemeyer, Emily D.
Journal of Chemical Education, v82 n11 p1682-1685 Nov 2005
A laboratory experiment reinforces the concept of acid-base equilibria while introducing a common application of spectrophotometry and can easily be completed within a standard four-hour laboratory period. It provides students with an opportunity to use advanced data analysis techniques like data smoothing and spectral deconvolution to conceptualize the equilibrium that exists between the acidic and basic forms of an indicator.
