摘要
“外生内规则”是应用电极电势来判断氧化还原反应的方向的一种方法 .对于φ 氧化态 /还原态 >φ 氧化态!@/还原态!@,则可发生反应为 :氧化态 +还原态!@→还原态 +氧化态!@即两外生成两内 ,其余的两内或一内 ,一外都不反应 .此规则简单、形象、易懂、易记、易掌握 ,便于应用 。
The rule for making decision by external elements instead of by internal ones is a new method to determine the direction of redox reaction by means of electromotance and electroelements. In the case of φ oxidation state / reduction state > φ oxidation stateˊ / reduction stateˊ , the reaction is found to be : oxidation state + reduction stateˊ → reduction state + oxidation stateˊ ,i.e., the two internal elements come from the two external ones . The two internals or either of the internals or externals won' t get involved in the reaction. Such a method is simple and easy to understand and apply while superior to some other methods
