Abstract
The standard potentials of the Ag-AgCl electrode in eighteen 2-propanol + water solvent mixtures at nine different temperatures from 15 to 55°C have been determined from the electromotive force measurements of the cell Pt, H
2 (gas, 1 atm); HCl (m), X% 2-propanol, Y% water; AgCl, Ag. The temperature variation of the standard potential was utilized to calculate the standard thermodynamic functions for the cell reaction, the primary medium effects of various solvents upon HCl and the standard thermodynamic quantities for the transfer of 1 mol of HCl from water to 2-propanol + water solvents. the significance of the data has been discussed in terms of the acid-base properties and the structure of water and of mixed solvents on the transfer process.
