近些年来,围绕钠及其化合物的性质设计实验试题,对考生进行实验能力测试,已成为高考的重点和热点.总的看,此类实验试题沿着两条主线进行命题,一是取材实验探究,考查钠及其化合物的基本知识、信息获取和加工能力、实验设计能力、实验评价能力等;二是模拟现实生 In recent years, the design of test questions around the nature of sodium and its compounds, test the ability of candidates to test has become the focus of the entrance examination and hot spots. Overall, these experimental questions along the two main lines of proposition, one draw experiment Explore, examine the basic knowledge of sodium and its compounds, information acquisition and processing capabilities, experimental design capabilities, experimental evaluation capabilities; the second is to simulate real-life
