| Abstract: | Using the Ringbom equation for titration of dibasic acids, the first and second titration jumps were derived. As followed, the accurate conditions for sequential titration of dibasic weak acids were derived with the first and second titration jumps. And the deduction is also applied to titration of polyprotic acids. |
