一般说来,实验组合题是指给出实验基本要素(如仪器、药品、试剂等)和基本知识,完成实验任务,达到实验目的与要求的综合性实验题。根据实验原理、实验目的的不同,可以分为装置的组装、原理的确定、完整实验过程的设计等类型。该题型对于考查学生的实验设计能力、操作能力和有关物质的制取、提纯、净化、验证等方面的综合能力起着极其重要的作用。
In general, the experimental combinatorial questions refer to the comprehensive experimental questions that give the basic elements of the experiment (such as instruments, drugs, reagents, etc.) and basic knowledge, complete the experimental task, and achieve the purpose and requirements of the experiment. According to the experimental principle and the purpose of the experiment, it can be divided into the assembly of the device, the determination of the principle, and the design of the complete experimental process. This question type plays an extremely important role in examining students’ experimental design capabilities, operational capabilities, and comprehensive ability in the preparation, purification, purification, and verification of related substances.
