Abstract:The thermodynamic properties of potassium and ammonium
dihydrogenophosphate
aqueous solutions and equilibrium solubility were investigated at
a temperature of 298.15 K. The calculated solubility required the
thermodynamic properties of the ternary system. Then, the water activities
were measured at molar concentrations ranging from dilute to saturated
solutions of {yKH2PO4 + (1
– y)NH4H2PO4}(aq) and at various ionic strength fractions (y) using the hygrometric method. From these newly measured data, relevant… Show more
