The Exploration of Thinking Map in Chemical Analysis——Take the Determination of Cobalt Content in the Metal Component of the Sample as an Example
The purpose of holding the chemical experiment technology skills contest is to evaluate the knowledge understanding and skill mastery of the contestants through the experimental operation.The chemical analysis method is mainly used for quantitative analysis of samples.The experimental examination has many knowledge points and strong operability,which makes students have certain difficulties in practice.According to the characteristics of chemical analysis,mind mapping is introduced into practical teaching,and the application of mind mapping in chemical analysis is discussed by taking the determination of cobalt content of the metal component of the sample as an example.The practice shows that the application of mind mapping in the practice of chemical analysis can help learners quickly and accurately grasp the chemical analysis method and complete the detection task efficiently and quickly.
