| Abstract: | The hydrolysis equilibrium system of weak acid strong alkali salts is discussed,the relationship among the hydrolysis equilibrium constant of weak acid strong alkali salts,the concentration of metal ion and the pH value of solution is introduced,a new method of metal cationic seleclive electrodes is also introduced to determine hydrolysis equilibrium constant of weak acid strong alkali salts,and Ca 2+ selectie electrodes are used to determine the hydrolysis equilibrium constants of Na 2CO 3 and Na 2C 2O 4,the determination values are identical with the documentary ones. |
