| Abstract: | A general method and program to calculate pH values for any complex aqueous system has been developed in this paper. This method and program are based on basic equations of complex aqueous system, pH value being used as trial and error variable and the electric charge balance equation being used as checking equation. This method is generally acceptable, and it has advantages of simplicity and convenience to use. The speed of calculation by this method is rapid. Some results obtained by this method are tabled and compared with the values in literature, and the consistensy is good. |
