回顾历年的高考化学试题,实验题的考查方式灵活多样,多角度、多层次考查学生的能力。定量实验是指为深入了解物质和自然现象的量的特征、揭露各个因素之间的数量关系、确定某些因素的数值等进行的实验。随着理科综合能力测试对定量理性思维能力以及实验设计能力要求的提高,高考试题中对实验的考查可能会将以前是在定性实验基础上渗透定量的要求改为直接要求进行定量实验设计。如何获得快速的解题思路,必须熟悉定量实验的常见几种方法和可能考查的
Recalling the chemical examination of the college entrance examination over the years, test questions flexible and diverse test methods, multi-angle, multi-level examination of students’ abilities. Quantitative experiments are experiments conducted to gain insight into the quantitative characteristics of material and natural phenomena, to reveal the quantitative relationship among various factors, and to determine the values of certain factors. With the improvement of quantitative rationality and ability of experimental design in comprehensive ability test of science, the examination of experiment in the entrance examination of the college entrance examination may change the requirement of quantitatively permeating and quantifying on the basis of qualitative experiment to directly require the quantitative experiment design. How to get a quick way to solve problems, we must be familiar with several common methods of quantitative experiments and may examine
