Abstract

The partial molar enthalpies of mixing of NaHSO4 and KHSO4 have been measured at 528 K by dropping samples of pure compounds into molten mixtures of NaHSO4 and KHSO4 in Calvet calorimeter. From these values the molar enthalpy of mixing has been deduced.The same method has been used for the determination of the heat capacity of the two pure compounds in the solid and liquid states.The phase diagram of this system has been confirmed by conductometric and thermal analysis methods.By an optimization method the excess entropy of the liquid mixtures was also calculated.
