盐类水解是中学化学的重要内容,也是教学的难点之一。在教学工作中经常碰到学生在运用水解知识处理问题时,往往不知在什么情况下考虑水解。现就盐类水解的主要应用归纳如下。一、比较盐溶液中离子浓度的大小,要用到盐类水解知识。例100m10.1mol/L 醋酸与50m10.2mol/l 氢氧化钠溶液混和,在所得溶液中离子浓度由 Salt hydrolysis is an important part of secondary chemistry, teaching is also one of the difficulties. Often encountered in the teaching of students in the use of hydrolysis knowledge to deal with the problem, often do not know under what circumstances consider hydrolysis. Now the main application of salt hydrolysis are summarized as follows. First, compare the size of the ion concentration in salt solution, to use salt hydrolysis knowledge. Example 100m10.1mol / L acetic acid and 50m10.2mol / l sodium hydroxide solution mixed in the resulting solution ion concentration from
