Cryptand 111 was used as a chemical device acting as an automatic titrator by changing the pH with time inside a reaction vessel in a slow and irreversible way. The pKa of phenol red was determined spectrophotometrically by a completely automatic run, without the need for external input adjustments. The experiment is proposed as a model for automatic determination of thermodynamic parameters.

Abstract
Cryptand 111 was used as a chemical device acting as an automatic titrator by changing the pH with time inside a reaction vessel in a slow and irreversible way. The pKa of phenol red was determined spectrophotometrically by a completely automatic run, without the need for external input adjustments. The experiment is proposed as a model for automatic determination of thermodynamic parameters.File in questo prodotto:
