| Abstract: | Studies on the preparation and deduces the constitute about Co（ NH3 ）5 Cl ] Cl2. And at the same time,discusses some ubiquitous problems to students. For example, the low productrate, without getting the constitute of inner - bound chloric, the phenomenon of inspection on Co^2＋ is not evident when heat the product for twice. So we analyze the reason of problems and Summarize the key of succeed-fail in experiment and improve on the method of preparation. |
