氧化还原反应是一种电子得失(或转移)反应,其氧化还原当量可由下式求得: 氧化还原当量=分子量/总电子得失(或转移)数对无机物来说,得失电子数极易看出,计算当然简单。但对有机物来说,由于其结构复杂,一般多属电子转移,又可能涉及水解、断键等过程,其总电子得失(或转移)数很难看出,因而不得不借助于用直观法或其它方法先将反应方程式配平,再间接求氧化还原当量。如: The redox reaction is an electron loss (or transfer) reaction, and its redox equivalent can be obtained from the following formula: Redox equivalent weight = molecular weight / total electron gain (or transfer) number For inorganic substances, the number of lost and lost electrons is extremely easy to see Out, the calculation is of course simple. However, for organic matter, due to its complex structure, most of them are electron transfer, and may involve processes such as hydrolysis and bond breakage. The total number of lost and/or transferred electrons is hard to see, so they have to resort to intuitive methods or other methods. The method first trims the reaction equation and then indirectly seeks the redox equivalent. Such as:
