配平化学方程式目前已有多种方法,如“观察法”、“离子——电子法”、“氧化数(化合价)法”等。这些配平方法对于通常的不同类型的化学方程式配平都各有其优越性。但是我们也常常发现,对于一些较复杂、较特殊的化学方程式,以及一些价态不易判断的物质,如:C_1 O_5、CoS、SoCl_2等参与的化学反应方程式,上述配平方法在不同程度上都存 There are many methods for the calibration of chemical equations, such as “observation method”, “ion-electron method”, “oxidation number (valence) method” and so on. These trimming methods each have its own advantages over the usual different types of chemical formulation. However, we often find that for some more complex and specific chemical equations, and some valence state is not easy to judge the material, such as: C_1 O_5, CoS, SoCl_2 and other involved in the chemical reaction equation, the above-mentioned method of balancing to varying degrees
