离子反应是中学化学中一种重要的化学反应类型,是学生学习化学的重要内容,应用非常广泛,也是高考中的重点和难点、热点。在处理有关离子反应的题型时,会发现题意表明同一溶液存在多种微粒互相竞争反应,一般包括氧化还原反应、复分解反应和双水解反应等。那么是哪种类型的反应优先进行呢?对此,我们来进行探讨和分析。 Ion reaction is an important type of chemistry in secondary chemistry. It is an important part of students’ learning chemistry. It is widely used and is also a key and difficult point in college entrance examination. In dealing with the type of reaction on the ion, you will find that the problem was that the same solution exists a variety of particles competing with each other, including redox reactions, metathesis and double hydrolysis reaction. So what kind of reaction is the priority? In this regard, we come to explore and analyze.
