任何物质在反应过程中都是想方设法使自己变得更稳定些,在反应过程中,分解出什么物质要视周围反应物的需要和反应条件而定,一般总是尽可能分解出周围的物质或反应物最需要的物质(或者说总是尽可能分解出对周围的物质或反应物最有吸引力的物质),这一规律,不妨叫做物质的分解原理。例如:HMnO_4在碱性环境中就不可能分解出+2价锰的化合物 MnO,因为 MnO 的碱性比 MnO_2和 Any substance in the reaction process are trying to make themselves more stable, in the reaction process, what material decomposition depends on the surrounding reactants needs and reaction conditions, the general is always possible to decompose the surrounding material or Reagents most in need of material (or always try to break down the surrounding material or reactant most attractive material), this law may wish to call the decomposition principle of matter. For example: HMnO_4 in alkaline environment will not be able to decompose +2 manganese compound MnO, because MnO alkaline than MnO_2 and
