摘　　要：用水解反应的自由能变,计算了醋酸钠和氯化铵的水解常数和pH值.用耦合反应的自由能变,计算了醋酸铵和酸式盐(例如,磷酸二氢钠和磷酸氢二钠)溶液的pH值.用其质子传递反应的自由能变,计算了水解常数和水解度.The hydrolysis constant and pH value are calculated by free energy change of hydrolytic reaction of sodium acetate and ammonium chloride. The pH value of solution of ammonium acetate and acid salt (e.g. sodium dihydrogen phosphate, disodium hydrogen phosphate) has been calculated by free energy change of coupling reaction. Their hydrolysis constant and degree of hydrolysis are calculated by free energy change of proton transfer reaction.
