【Abstract】 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.更多还原
