| Abstract: | This paper derives an universal equation for calculating the pH value of a weak acid and weak base equilibrium system. This equation is based on the protou condition equation and distribution coefficient in a weak acid and weak base equi- librium system, with the influence of protonlysis of solvent water under consideration. A numerical solution on the equation is undertaken by using PAD programming technique so as to calculate accurately the pH values of weak acid and weak base equilibrium syctems. |
