摘要
本文提出一种基于滴定突跃的准确滴定判别方法,以统一方式完成不同滴定类型的判别。该方法具有原理明确、步骤简单、记忆负担轻和计算效率高的优点;当目测不确定性或者允许误差等参数发生改变时,计算效率不受影响。对于多组分复杂滴定体系,该方法同样高效,只是涉及的数值计算稍显繁复,然而通过软件也能够快速完成。该方法为准确滴定判别提供了一种不同于传统判别式的解决途径。
A universal solution is proposed to determine the feasibility of various types of titrations. This solution features unambiguous theory,simple procedure,low memorization,and high efficiency. The efficiency is not affected by changes of parameters such as visual uncertainty or allowance error. For multi-component titrations,the solution is also efficient despite complex calculations that can be completed quickly with the software developed by the author.This solution provides a different approach from the traditional formula-based one to determine the feasibility of titration.
