| 中文摘要: |
| 现有的酸碱滴定终点误差计算方法归为两类，一类是针对不同滴定体系提出不同的计算公式；另一类是仿造林邦误差公式，但不同体系的终点误差计算公式形式仍不相同。至今未有简明且通用的计算方法。本文从酸碱滴定反应的本质出发，首次明确提出了适用于所有酸碱滴定体系的终点误差计算方法，并做了深入的论证。即只需写出化学计量点时滴定产物的质子平衡式，左右两式之差即为滴定终点误差。简明通用，可大大简化相应的教学内容。 |
| 英文摘要: |
| There are two ways of error calculating for the acid-base titration. One includes diverse formulas for different titration systems. And the other copies the form of Ringbom error formula however is quite dissimilar for each other. No concise and universal means has been proposed yet. A general method is first produced according to the innate character of the acid-base reaction. That is to write the proton balance equation for the titration products at the stoichiometric point, the difference between two sides of the equation is just the end point error. It’s very simple and clear for all types of acid-base titration, and could reduce the corresponding content of courses significantly. |
