Activity coefficients measureme nt of KCl +KNO۳ +Water +Proline system b y Pitzer model at T=۳۰۳.۲ K

Thermo dynamic study of (sa lt+amino acid+water) system is useful to understand several bioche mical processes such as protein hydration, denaturation and aggregat on [۱]. Additionally, the presence of electrolyte solution s has great effects on the structure and properties of proteins. So, a more profo und understanding of the electrol yte effect on amino acid solutions is required [۲]. In this wo rk, the thermodynamic properties of the quaternary mixed electrolyte system (K Cl+KNO۳+ Proline+H۲ O), using the potentiometric method, are reported.
