对数图解法首先由B jerrum提出并用于滴定误差的计算.以后逐渐在斯堪的那维亚发展起来,但未引起广泛的注意.在有关书籍中虽相继提及,但阐述多较简略.我们觉得此法有如下特点:一、简单明了,不需要进行繁复的运算,作图也简便易行.二、在解决复杂的酸度计算时能提供可忽略的部分(这是采用一般计算方法时所必要的,否则要解高次方程).三、能解一般计算不易求解的某些酸度计算问题.四、应用较广泛.鉴于此,我们试通过一些实例阐述该方法的原理,并对在酸度计算方面的应用加以讨论.
The logarithmic graph method was first proposed by Bjerrum and used in the calculation of titration errors, but later gradually developed in Scandinavia, but did not attract wide attention. Although the books mentioned in succession, but the description is more simple. We think this method has the following characteristics: First, the simple and clear, does not require complicated calculations, drawing is also simple and easy. Second, to solve the complex acidity calculation can provide negligible part (this is the general calculation method Necessary, or to solve the high degree equation.) Third, to solve the general calculation is not easy to solve some acidity calculation problems. Fourth, the more widely used In view of this, we try to illustrate the principle of the method through some examples, The application of acidity calculation is discussed.
