多元酸碱滴定平衡参数的连续求解

Continuously Calculating for Equilibrium Parameters of Polyprotic Acid-Base Titration

由多元酸碱滴定过程的质子条件导出有关参数随酸度变化的函数关系,用BASIC语言编制计算机程序,可连续求解强碱滴定多元酸或强酸滴定多元碱时,在任一酸度下的型体分布系数、平衡浓度、滴定分数、滴定缓冲容量和滴定过程锐度指数等平衡参数·给出了算法框图及应用实例.

From the proton condition of polyprotic acid-base titrating process, a conventional parameter set was deduced to calculate species distribution fraction,equilibri- um concentration, titration fraction, buffer capacity and sharpness index, ect., of polyprotic acid-base titration in a assigned pH continuously. The computer-oriented brief flowchart and results illustrations were given.
