| 英文摘要 | the molar heat capacities of aqueous na2b4o7 solution with concentration of 0.033 55 mol . kg(-1) were measured by a precision automated adiabatic calorimeter in the temperature range from 78 k to 351 k. the fusion transition at t=272.905 k was observed from the heat capacity measurements. according to the polynomial equations of heat capacity as a function of temperature and thermodynamic relationship, the thermodynamic functions (h-r-h-298.15k) and (s-r-s-298.15 (k)) of the aqueous borax decahydrate solution were derived in the temperature range from about 80 to 350 k with an interval of 5 k. the molar enthalpy and entropy of the phase transition were determined to be 4.536 kj . mol(-1) and 16.62 j . k-1 . mol(-1). the activity of the solution was determined to be 0.997 63 by using the freezing point depression of the solution based on the liquid-solid phase equilibrium rule. |
