物质之间发生化学反应始终遵循自然规律,也体现了化学是自然学科的特点。化学反应的自然规律也就是活泼性强的物质向活泼性弱的物质转化,由酸碱性强的物质向酸碱性弱的物质转化,由氧化性或还原性强的物质向氧化性或还原性弱的物质转化等,实际上体现了大自然规律物质由不稳定状态向稳定状态变化。离子反应原理是中学化学重要内容,离子间发生复分解反应是最常见的反应类型,此类包括的反应类型主要有:复分解反应、水解反应、络合反应,还包括由溶解度大
Chemical reactions between substances always follow the laws of nature, but also reflects the characteristics of chemistry is a natural subject. The natural law of chemical reaction is the lively material to lively and weak material conversion, from acid to alkaline substances to the weak acid-base material, the oxidation or reduction of strong substances to oxidation or reduction In fact, it reflects the change of the law of nature from the unstable state to the steady state. The principle of ion reaction is an important part of chemistry in middle school. The most common type of reaction is the metathesis reaction between ions. The main reaction types include: metathesis reaction, hydrolysis reaction, complexation reaction,
