Analysis of aqueous solutions by near-infrared spectrometry (NIRS). I. Titrations of strong acids with strong bases.
The titrn. of 1 M HCl with 2 M NaOH was obsd. by NIR-spectrometry. The measured spectra can be evaluated quant. for calibration of the H+- and OH--concn. The NIRS errors with respect to the prediction of the pH and the equivalence point are discussed.
