《盐的水解》是中学化学的基础理论之一。在教学中,有些问题在学生中容易造成混淆。本文拟就中学化学教学中涉及的有关问题,进行初步探讨。一、盐类水解反应的可逆性盐的水解反应物之一——水是极弱的电解质,因而水解反应是可逆反应,它的逆反应是中和反应如下式: Salt hydrolysis is one of the basic theories of middle school chemistry. In teaching, some problems are easily confused among students. This article intends to conduct a preliminary discussion on the issues involved in chemistry teaching in middle schools. One of the reversible salts of the hydrolysis reaction of salt hydrolysis of one of the reactants - water is a very weak electrolyte, so the hydrolysis reaction is a reversible reaction, its reverse reaction is the neutralization reaction as follows:
