复分解反应是化学反应中重要的反应类型之一,是初中化学的重点也是学习的难点,是学好酸碱盐知识的关键之一,因此必须理解并会应用复分解反应解题.复分解反应是两种化合物通过相互交换成分,生成另外两种化合物的反应,其反应形式为AB+CD=AD+CB.1.明显的特点是“双交换,价不变”1两种化合物反应,生成另外两种化合物的反应不一定都是复分解反应.如:2Na OH+CO2=Na2CO3+H2O该反应不是复
Metathesis reaction is one of the important reaction types in chemical reaction. It is one of the key points to learn the knowledge of acid-base salt because it is the key point of junior high school chemistry. It is necessary to understand and apply the problem of metathesis reaction. Two kinds of metathesis reaction The compounds react with each other to form the other two compounds in the reaction form AB + CD = AD + CB.1. The obvious characteristic is that the “double exchange, constant price” reaction of the two compounds generates additional The reactions of the two compounds are not necessarily metathesis reactions such as: 2Na OH + CO2 = Na2CO3 + H2O The reaction is not complex
