摘要
用电位滴定法测定醋酸浓度的实验表明,在3种确定终点的方法中,二阶微商法准确度更高,同时该法还具有简便、快速等优点,电位滴定法比普通手动滴定法的平均偏差小,精密度高,准确度高.
An electrometric titration method for acetic acid concentration is described. It is simplest, the most accurate, and fastest among the three approaches. And it has low average deviation, high accuracy compared with the common manual tittering.
