高锰酸盐与草酸盐的反应是本研究的第一部分的主题，它被证明具有复杂的性质，实际上是由几个不同的反应组成的，因此有必要寻求一个更简单的化学变化的例子来研究。所选择的反应必须同时联合收割机结合前面列举的所有其他条件，以便有可能连续地改变它的条件并测量它的条件和它的量。在尝试了几个似乎合适的反应之后，在提出的研究方法中经常被一些实际困难所挫败，我们终于成功地为一个非常简单的化学变化案例设计了一种既容易又准确的研究方法。反应是过氧化氢和碘化氢的反应，H2O2+2HI = 2H2O+I2。
The reaction of hydric permanganate upon hydric oxalate, which formed the subject of the first part of this inquiry, having proved to be of a complex character, consisting in fact of several distinct reactions, it became necessary to seek for investigation a simpler case of chemical change. The reaction selected must at the same time combine all the other qualifications before enumerated, that it might be possible successively to vary its conditions and to measure its conditions and its amount. After making trial of several reactions which appeared suitable, and being as often foiled by some practical difficulty in the proposed methods of investigation, we at last succeeded in devising for a very simple case of chemical change a method of investigation at once easy and exact. The reaction is that of hydric peroxide and hydric iodide, H2O2+2HI = 2H2O+I2.
