摘要
酸解离常数是各种弱酸重要的物理常数,用电位法测定酸解离常数通常需要涉及到繁琐的数学计算,将Bjerrum生成函数变形,通过建立线性方程组的方法是计算多元酸解离常数的常用方法。利用Excel强大的数据运算功能和电子表格功能,不仅避免了手工计算和编程的麻烦,使滴定数据的处理变得非常简便,提高了效率,而且结果更为精确和可靠。
Acidic dissociation constant is a significant characteristic of weak acid. The determination of acidic dissociation constants by electric potential titration involves complicated calculation. The most common calculation method includes reformation of Bjerrum' s formation function and therefore simultaneous linear equation. By the application of Excel worksheet in the data processing, manual calculation and computer procedure is avoided. The data processing is becoming simpler and efficiency, and the result more accurate.
