摘　　要：从解离平衡、水解效应、共轭酸碱的缓冲效应、质子条件式、物料、电荷守恒关系入手建立相应的数学表达式,选出科学、合理的数学关系式跟踪计算滴定过程溶液pH变化情况。利用典型数据化学计量点、滴定突跃的pH,优化滴定方案。From dissociation equilibrium,hydrolysis,conjugate acid-base buffer effects,proton balance equation,materials,and charge conservation relationship starting with the establishment of appropriate mathematical expressions,scientific and reasonable mathematical formula for tracking calculation of selected variation of pH during the titration solution.Using typical data for stoichiometric point and pH of the break,titration scheme was optimized.
