酸的强度的定义,我们的意见常常不是一致的。只要不超过一定范围,各种强酸,如果浓度一样,它们的 P_H 值也就一样,分别不出强弱来。我们不得不利用有氢离子参加的一些物理化学现象直接来规定酸的强度。这些物理化学方法,通常分为两种:——(Ⅰ)动力学方法,例如(1)葡葡醣 C_6H_(12)O_6,的旋光度的 The definition of acid strength, our opinions are often not the same. As long as no more than a certain range, a variety of strong acids, if the same concentration, their P_H value is the same, respectively, no strength to come. We have to use some of the physical and chemical phenomena that hydrogen ions participate in to directly specify the acid strength. These physicochemical methods are generally divided into two types: - (I) Kinetic methods such as (1) the optical rotation of glucose C 6 H 12 O 6
