Abstract In the present paper, the authors tried to discuss the conditions that metallochromic indicator should meet and the application of indirect metallochromic indicator based on an example of analytical chemistry. Furthermore, the authors tried to analyze a few problems which needed to pay attention and the relative solutions in back titration combined with practical examples. The purpose was to help students to understand the essence of the example, to enlighten divergent thinking, to draw inferences about other cases from one instance, and to improve learning efficiency and scientific thinking ability.
