高考化学学科试题对实验能力的要求之一,就是要具有对观察、记录到的实验现象、实验结果和测得的数据进行分析、处理,并得出正确结论的能力。这就要求我们的学生在实验复习中,要对实验操作中的细枝末节给予高度的关注,把握好“细节”与“关键点”。一、实验方案设计的一般原则科学研究过程中,一个相对完整的化学实验方案一般包括以下内容:(1)实验名称;(2)实验目的;(3)实验原理;(4)实验用品(仪器、药品及规格);(5)实验步骤(包
One of the requirements for college entrance examination chemistry subject test ability is to have the ability to analyze, process and obtain the correct conclusion on observed and recorded experimental phenomena, experimental results and measured data. This requires our students in the review of the experiment, we should pay great attention to the minutiae in the experimental operation, grasp the “details” and “key points.” First, the general principle of the experimental program design In the process of scientific research, a relatively complete chemical experiment program generally includes the following: (1) the name of the experiment; (2) the purpose of the experiment; (3) experimental principle; (4) experimental supplies , Drugs and specifications); (5) experimental steps (package
