酸碱中和滴定分析中的误差

摘要

As a quantitative analytical method, acid and alkali neutral titration has been widely used in titration analy- sis for its simple, rapid and higher accuracy characteristics. It is proved that the measurement precision degree is al- ways restricted by instruments and operation methods, and the errors always exist between the experimental data and true value. How to direct titration end point more accurately and reduce the operating errors becomes the key of success or failure.%作为滴定分析中应用广泛的一种测量物质含量的方法，酸碱中和滴定是一种简便、快速和应用广泛的定量分析方法，在常量分析中有较高的准确度。大量实验证明，任何测量的精确程度总是受到来自仪器和操作方法等方面的制约，测得的值与真实值相比总有误差。实验中如何更准确的确定终点，减少操作中带来的误差，成为实验成败的关键。
