摘要:
弱酸的一对共轭型体的两条分布曲线移到pH-δA,δHA坐标系上,二曲线便互相重合,成为一条共轭分布曲线,也是酸碱平衡曲线。结合该图像讨论了滴定过程,得知几条平衡曲线作为原始线合成滴定曲线,以及滴定曲线形状特征的由来。
关键词: 滴定曲线方程, 共轭曲线, 滴定分数
Abstract:
The two distribution fraction curves of a weak acid and its conjugated base are integrated to the pH-δA, δHA coordinate system. The two curves coincide with each other to form a conjugate distribution fraction curve, which is also an acid-base equilibrium curve. The titration process is discussed with images to understand how a specific equilibrium curve to a titration.
Key words: Titration curve equation, Conjugate curve, Titration fraction
