一元强碱滴定二元弱酸的林邦滴定曲线方程及pH_(sp)计算

The Ringbom Equation for the Titration Curve of Diprotic Weak Acid by Monoprotic Base and pH_(sp) Calculation

用质子条件式PBE、物料平衡式MBE、副反应系数和条件稳定常数等知识,推导出一元强碱滴定二元弱酸溶液的林邦滴定曲线方程,并用其推导出第一、第二化学计量点pH_(sp1)和pH_(sp2)的计算公式。

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 （pHsp1） and the second （ pHsp2 ） stoichiometric point were deduced subsequently.
