能水解的盐溶于水后,因发生水解反应而使溶液中离子的数量发生变化,学生在解答这类问题时,仅仅根据水解方程式去判断离子的变化情况,常常会得出错误的结论,例:等物质的量浓度等体积的NaCl和CH_3COONa深液中,离子数目的关系如何,有些同学认为,NaCl不 When the hydrolyzable salt dissolves in water, the amount of ions in the solution changes due to the hydrolysis reaction. When students answer such questions, they only judge the change of ions based on the hydrolysis equation, often resulting in erroneous conclusions. Example: The concentration of substances such as NaCl and CH_3COONa in the deep liquid of equal volume, the relationship between the number of ions, some students believe that NaCl is not
