摘　　要：锰元素的化学性质在不同介质、不同氧化态时表现出较大差异,其变化规律不易把握.从热力学角度利用锰的自由焓-氧化态图可以对它在水溶液中的相对稳定性、歧化反应发生的可能性、氧化还原反应进行的趋向性以及氧化还原能力大小等性质进行判断,对锰及其化合物化学性质的变化规律能进行直观的概括.The chemical property of the manganese （Mn） element varies evidently in different medium and oxidation state, so it is difficulty to control its rules of transformation. Based on thermodynamics, the judgment of its chemical property can be carried on by using its free enthalpy-oxidation state chart, including a relative stability in the water solution, the possibility of disproportion, the tendency and ability of the deoxidization reaction as well as the oxidation reaction, and getting a summary about the transformation rules of the manganese and its compounds＇ chemical properties.
