盐类水解问题是中学化学的重点和难点,也是高考命题的热点,我们应在化学平衡、电离平衡理论的支持下去探究盐类水解的实质、规律。时刻把握:有弱才水解,越弱越水解,谁强显谁性。同时理解盐类水解在生产、生活中的应用。考点1.盐类水解平衡移动盐类水解平衡受温度、浓度、溶液等酸碱性等外界条件的影响,并遵循勒夏特列原理。
Salt hydrolysis problem is the focus of high school chemistry and difficult, but also the hot topic college entrance examination, we should chemical equilibrium, ionization equilibrium theory to explore the nature of salt hydrolysis, the law. Grasp the moment: a weak ability to hydrolysis, the weaker the more hydrolysis, who was strong who. At the same time understand the salt hydrolysis in the production, life’s application. Test points 1. Salt hydrolysis balance Mobile salt hydrolysis balance by the temperature, concentration, pH and other external conditions such as solution, and follow Le Chatelier principle.
