Effect of Solvent on Protonation Equilibria of L-Proline and L-Valine in 1, 2-Propanediol-Water Mixtures
Protonation equilibria of L-proline and L-valine in varying compositions (0.0-60.0% v/v) of 1, 2-Propanediol-water mixtures were investigated pH-metrically. Titrations were performed at 303.0 K and the ionic strength of the medium was maintained at 0.16 mol L-1 using sodium chloride. The best fit ch...
