综合实验题是高考化学试卷中的必考题也是学生难以突破的一道题。综合实验题考查内容全面,从定性判断到定量分析、从化学原理到实际操作、从无机到有机都有涉及。主要考查化学常见仪器的使用、物质的分离、除杂、提纯的方法;物质的检验、制备、性质的验证;化学性质递变规律与化学反应规律的研究,实验方案的设计与评价等内容。每个问题之间有一定联系,但不紧密,带有一定的独立性。如果能掌握此类问题的解题策略,对培养学生的思维能力和分析、解决问题的能力大有裨益。
Comprehensive test questions is the entrance exam papers in the exam is also a difficult problem for students to break through. Comprehensive test questions examine the contents of a comprehensive, from qualitative judgment to quantitative analysis, from the chemical principles to the actual operation, from inorganic to organic are involved. The main test chemical common use of the instrument, the separation of substances, impurity removal, purification methods; material testing, preparation, the nature of verification; chemical laws of chemical laws of change and the reaction of the experimental design and evaluation of the program content. There is a certain connection between each issue, but not close, with a certain degree of independence. If you can grasp the problem solving strategies for such issues, to develop students’ thinking ability and ability to analyze and solve problems greatly beneficial.
