摘要
借助数轴透析"一种金属与溶液中多种盐反应"和"多种金属与溶液中一种盐反应"中溶质与滤渣的组成,直观地将反应进程和结果展现其中,建立思维模型,化难为易,有利于学生掌握与应用。
The composition of solute and filter residue in"one metal reacts with a variety of salts in solution"and"one salt reacts with a variety of metals in solution"were dialyzed by the aid of number axis.It intuitively showed the reaction process and results,established a thinking model,and made it easy.It was good for students to master and apply.
