综合实验题通常将原理与操作、方法与步骤、分离与鉴别、实验目的与方案设计、实验现象与解释(反应原理)、产物推断与含量计算等联系起来考查,题材新颖,难度较大·解题时要求学生“会设计、会推算、会操作、会表达”,它集实验知识、实验操作及实验能力于一身,大大地提高了实验 The comprehensive experiment questions are usually related to principles and operations, methods and procedures, separation and identification, experimental purposes and program design, experimental phenomena and interpretation (reaction principle), product inference and content calculation, etc. The subject matter is novel and difficult to solve. Students are required to “design, calculate, operate, and express”. It combines experimental knowledge, experimental operations, and experimental capabilities to greatly improve the experiment.
