Abstract
The dissociation constants of amino acids are generally determined by acid-base titration and by the emf method. The use of the conductimetric method to obtain pK for amino acids appears to be the first of its kind. In this study, we describe the method of measurement, the treatment of the data and discuss the results. The choice of MOPSO for the investigation is in conjunction with the development of new buffer systems as pH Standard Reference Materials. The value for pK at 25°C is 0.060±0.005.
