Compared to Potentiometric methods, the spectrophotometric determination of formation constants, aided by computer-based data analysis, has not been extensively developed. The reasons are several, including the apparently lower accuracy of spectrophotometric data; the much larger amount of data generated by digitizing the spectra; numerical problems associated with data processing; lack of precision (compared to Potentiometric investigations) of the refined constants.
