Thermodynamics for proton binding of phytate in KNO3(aq) at different temperatures and ionic strengths

Thermodynamic protonation parameters were also obtained at different temperatures and ionic strengths. The proton association process is slightly exothermic and the enthalpic contribution is less negative than that in NaCl solution. As observed in other cases for phytate anion, the major contribution for the proton association is entropic in nature. A rough value of Δcp was also determined. Finally, a complete set of suggested data is proposed at different temperatures and ionic strengths.
