【摘要】 针对锰的氧化态多样、颜色变化丰富的特点,引导学生重点对锰(VI)和锰(Ⅲ)的生成与歧化反应的转化条件进行了试验,对试剂用量、反应温度、溶液pH值等影响反应方向与现象的因素进行了探讨,并对研究性实验教学问题浅述见解。更多还原

【Abstract】 Oxidation states and colors varying are a important character of compounds of Manganese. We designed a serial of experiments that discus the condition of disproportionation and formation Mn(Ⅲ) and Mn(Ⅵ).Probe into the effect factors of reaction direction by changed dosage of reagents,temperature,concentration,and acidity.Put forward some thinking for teaching method in studying experiment teaching.更多还原
