The potentiometric measurements were made at 25 and 37 �C using the cell type: Pt, H2 (g, 1 atm)|BUFFER (m1) + NaBUFFERate (m2) + NaCl (m3)|AgCl, Ag. The values of ?-Cl and pH for an isotonic saline media (I = 0.16 mol�kg-1) of nine physiological buffer solutions have been calculated using the Bates-Guggenheim convention, Pitzer formalism, and extended Debye-H�ckel equation. Based on the Pitzer convention, pH values of biological buffers will be recommended as secondary standards.

Comparison of the pH data using Pitzer model, Bates-Guggenheim convention, and extended Debye-H[uuml]ckel equation for the calculation of the single-ion activity coefficient, γ<sup>-</sup><sub>Cl</sub> for biological standard buffer solutions of ACES, TRICINE, and MOPS at 25 and 37 °C
