化学是一门以实验为基础的学科,化学实验在高中化学教学中占有举足轻重的地位,化学实验是探究化学反应现象及规律的教学方法,通过化学实验可以让学生认识到化学反应的本质。因此化学实验的考察是高考试题中必不可少的一部分,而且分值较高。纵观近几年安徽的高考试题,七道选择题中有一题涉及实验内容;四道大题中有一题是实验探究 Chemistry is an experiment-based discipline. Chemistry experiments occupy a pivotal position in chemistry teaching in senior high schools. Chemistry experiments are the teaching methods to explore phenomena and laws of chemical reactions. Students can recognize the essence of chemical reactions through chemistry experiments. Therefore, the study of chemical experiments is an essential part of the college entrance examination questions, and score higher. Throughout the Anhui college entrance examination papers in recent years, one of the seven multiple choice questions involves the content of the experiment; one of the four major problems is an experimental study
