测定醋酸电离度和电离常数的两种微型方法的比较研究

Acetic Acid Ionization and The Determination of Ionization Constants of The Comparative Study of Micro-ways

本文用两种微型的实验方法,测定了常温下醋酸的电离度和电离常数。通过分析、对比,得出最佳的测试方法为pH值法。该方法具有试剂用量少、实验时间短、污染少、实验操作安全等优点,并体现了绿色化是化学实验教学发展的必然趋势,是减少实验室废弃物和环境保护的最佳选择。

In this paper, two micro-experimental method to determine the ambient temperature at the ionization of acetic acid and the ionization constant. Through analysis, comparison of the test to draw the best way is to experiment in the micro-pH value. The method is to use less reagent, experimental time is short, less pollution, the advantages of the safe operation of the experiment. This method reflects the green chemistry experiment chemistry experiment teaching is the inevitable trend of development is to reduce waste and environmental protection in the laboratory the best selection.
