摘要
本文建立了NaOH滴定混合酸过程中[H]随滴定剂V变化的微分滴定方程,选用龙格一库塔(Rung-Kutta)算法求解上述微分方程,从而进行pH随△V变化的动态模拟计算.本文将离子的活度系数引入计算过程,因而获得了与实验值吻合的模拟计算结果.
A differential titrating equation for the acid mixture with strong base was established. With the Rung-Kutta algorithm, we use the equation to calculate the change of pH by the change of AK of titrant for dynamic state simulation. The activity coefficient was used in the calculation process, and the results compared with experimental ones are similar.
