The Ringbom equation for the titration curve of diprotic weak acid by monoprotic base was developed based on the proton balance equation, the mass balance equation, the side reaction coefficient, and the conditional stability constant.The calculation formulas for the first(pH_sp₁) and the second(pH_sp₂) stoichiometric point were deduced subsequently.
- Acid-base titration,
- Side reaction coefficient,
- Conditional stability constant,
- Titration curve equation
