Abstract:

Taking classical synthetic experiments, the syntheses of potassium dioxalatocuprate (Ⅱ) dihydrate and potassium trioxalatoferrate (Ⅲ), as examples, this article discusses the effects of synthetic conditions on the "quality" and "quantity" of the product. Moreover, a flowchart clearly shows the cases when the students fall into a wrong path due to the lack of rethinking and judgement during the synthesis of potassium trioxalatoferrate. The article also discusses on how to inspire students to analyze when they were misguided. Therefore, this article reveals on how to educate students to think and criticize in the teaching process.

Key words: Chemical laboratory teaching, Classical synthetic experiment, Thinking, Criticizing
