摘要
以较复杂的EDTA六元酸、铜氨配合物为例,利用Origin软件简单快速地绘制酸碱平衡和配位平衡中弱酸和配合物各种存在形式随酸度和配体浓度变化的分布曲线.这将为分析化学中分布曲线的绘制提供一种方法,并且该法对学生准确而深入理解分布分数和分布曲线具有重要的帮助.
EDTA （ hexahydric acid ） and Cu-ammine complex were as examples, and Origin software as an easy and rapid tool was applied to plot distribution curves of different species of weak acid and base, coordination complexes with concentration variations of acid and ligand in acid-base balance and coordination balance. This will be a useful method to plot distribution curves in analytical chemistry and help students to deeply and accurately understand distribution fraction and curves.
