在传统的“应用广泛的酸碱盐”教学中,我们发现有的学生疲于应对数量众多的化学方程式,即便会写但在真正做题的时候却不太会运用.原因是学生对酸碱盐反应的本质以及相互之间反应的联系掌握不到位,于是我们可以从物质反应的本质入手,帮助学生分析反应前后的微粒,在反应中哪些微粒发生了改变,从一种物质的性质掌握一类物质的反应,举一反三,从而将溶液知识和微粒紧密联系起来,帮助学生实现在宏观物质和微观粒子之间的穿越,打破
In the traditional “widely-used acid-base salt” teaching, we find that some students are struggling to cope with a large number of chemical equations, even when they write but do not really use it when they really do it The nature of the acid-base reaction and the relationship between the reaction is not in place, so we can start from the substance of the reaction to help students analyze the particles before and after the reaction, which particles in the reaction has changed from the nature of a substance Master a class of material reaction, give top priority to one another, so that the solution of knowledge and particles closely linked to help students achieve the cross between the macroscopic material and microscopic particles, breaking
