盐不仅是酸碱中和反应的产物,许多化学反应都有盐生成,以盐为中心可以把有关的零散的知识系统化,这类中考题既考查了学生基础知识的掌握情况,又培养了学生总结归纳能力,现就2011年中考试题研究之.例1(2011年四川省眉山)某同学对酸碱盐的知识进行了以下的梳理.(1)填写下表空格中的化学式:反思:根据以上盐中的金属元素的排列,可以得出是依据——顺序归纳整理的.(2)为理解稀盐酸和氢氧化钠两者之间 Salt is not only the product of acid-base neutralization reaction, many chemical reactions have salt formation, and the salt-centered can systematize the related scattered knowledge. This kind of middle-level exam questions the mastery of students’ basic knowledge and cultivates The students summarize their abilities and are now studying the PEC exams in 2011. Example 1 (Meishan, Sichuan Province, 2011) A classmate classifies the knowledge of acid-base salts as follows: (1) Fill in the chemical formula in the following table: Reflection: According to the above arrangement of the metal elements in the salt, it can be concluded that the order is summarized according to - (2) To understand the difference between dilute hydrochloric acid and sodium hydroxide
