Notes: Abstract The ionization constant of benzoic acid has been determined by conductivity measurements of dilute aqueous solutions and found to vary from 6.27×10−5 at 25°C to 0.39×10−5 at 250°C. The pressure effect to 2000 bar has been measured, and the ratio of ionization constants K2000/K1 is 2.26 at 25°C and 7.3 at 250°C. ΔV°1, the standard partial molar volume change for the ionization at 1 bar, varies from −11.7 cm3-mol−1 at 25°C to −60 cm3-mol−1 at 250°C. The volume changes are smaller at higher pressures.

Notes: Abstract The ionization constant of ammonia has been determined by conductivity measurements and found to vary from 1.77×10−5 at 25°C to 1.3×10−6mol-kg−1 at 250°C. The pressure effect to 2000 bar has been measured and the ratio K2000/K1 is 6.8 at 25°C and 11 at 250°C. The standard molar volume change for the ionization at 1 bar, ΔV 1 o , changes from −28.8 at 25°C to −67 cm3-mol−1 at 250°C.

Keywords: Ionization constant ; orthophosphoric acid, conductivity, volume of ionization ; high temperature ; high pressure
Source: Springer Online Journal Archives 1860-2000
Topics: Chemistry and Pharmacology
Notes: Abstract The ionization constant of orthophosphoric acid, determined by conductivity measurements, decreased from 7.11×10−3 at 25°C to 6.2×10−4 mol-kg−1 at 200°C. The pressure effect to 2000 bar was also measured and the ratio K2000/K1 is 2.7 at 25°C and 3.7 at 200°C. The standard partial molar volume change for the ionization at 1 bar, $$\Delta \overline V _{_1^o }$$ , changes from −16.1 at 25°C to −33.3 cm3-mol−1 at 200°C. The partial molar compressibility change for the ionization, $$\Delta \overline x ^\circ$$ , varies from −3.8×10−3 to −8.3×10−3 cm3-mol−1 bar−1 over the same temperature range.
